On State Road 46 in Brown County, there is a small gas stop that people drive more than an hour to reach, and fuel is not the reason. They come for a breaded pork tenderloin sandwich that some online pages call the best in Indiana.
From the road, the building looks plain enough to pass without a second glance. Inside, a busy kitchen turns out tenderloins, battered mushrooms, onion rings, and fried pickles at prices that still feel fair.
Weekend travelers heading to and from Brown County State Park often build their whole route around a stop here. Read on to learn where it is, what to order, when the doors open, and why so many people slow down for one sandwich.
A Gas Station With a Secret on State Road 46
The sign out front says Gnaw Mart, and the store itself is filed under convenience store. Its home is 4947 IN-46, Nashville, IN 47448, in the Gnaw Bone area of Brown County, Indiana.
State Road 46 is the main route linking Columbus, Nashville, and Bloomington. That makes the store a natural stop for anyone crossing the county by car or motorcycle.
Here is the twist. Behind the gas pumps and snack aisles sits a hot food counter that has built a loyal following of its own.
The store carries a 4.5-star average across more than 300 opinions online. The single most talked-about item is the tenderloin sandwich, mentioned far more often than anything else on the menu.
Friendly staff come in a close second. Few gas stations earn that kind of attention for both their food and their people.
So the question is simple. How did a roadside mart become a destination in its own right?
Plain Outside, Busy Inside
Nothing about the exterior shouts for attention. It looks like a humble gas station, and plenty of first-timers almost drive right by.
Locals have a piece of advice for newcomers. Slow down, or the turn will come and go before you notice it.
Once inside, the store does double duty. Shelves hold snacks and essentials, and the pumps outside handle the fuel side of the trip.
The place is known for staying clean and well stocked. That matters when a stop is meant to cover gas, a meal, and road supplies all at once.
Toward the back, there is an eating area where guests can sit and relax with their food. It is not fancy, and it does not try to be.
That modest setup is part of the charm. The building keeps expectations low, and the kitchen keeps exceeding them, one basket at a time.
The Tenderloin That Built a Reputation
Indiana takes its breaded pork tenderloin seriously, and this sandwich sits near the top of many fans’ lists. Some online pages frequently name it the best in the state.
The sandwich is big. One past order described a full tenderloin measuring roughly five by ten inches, served on a bun with toppings.
Fans praise the meat as thick and consistent all the way through. Several point out that they found no gristle or hard pieces.
The breading gets credit for being fried just right. The bun earns compliments too, though not from everyone.
A half tenderloin is also available for lighter appetites. In the past, it was described as plenty for one person on its own.
Not every experience is perfect. A few people have called the sandwich good rather than great, and one disappointed customer wished a grilled version were offered.
Still, the overall verdict leans strongly positive. For most travelers, this is the sandwich that justifies the detour.
Mushrooms, Pickles, and the Fried Supporting Cast
Ask a regular what to order besides the tenderloin, and breaded mushrooms often come up first. Some fans call them the best they have ever had.
Fried pickles share top billing. One yearly Brown County regular ranks the mushrooms and pickles as must-haves, saying they are hard to match anywhere else.
The batter gets special praise. The kitchen also seasons its vegetables, which helps them stand apart from standard fried sides.
Onion rings appear often in conversations about the menu. Fans like that the onion stays inside the breading.
Fried okra, fries, and homemade chips round out the lineup. Cheese sticks are on offer as well, though one picky eater found them skippable.
Fish, chicken tenders, pulled pork, and corn dogs also turn up on orders. Kids especially seem happy with the tenders.
With so many options, the side dishes almost deserve their own road trip.
A Sauce With Attitude
Some sauces are just condiments. Then there is the one called sassy sauce.
Its name alone invites a little fun, and people who feel a bit sassy themselves seem eager to try it. It pairs especially well with the battered mushrooms.
Fans recommend it as a top choice for dipping. It comes up again and again alongside the fried sides.
There is another tip worth trying. One regular suggests ketchup blended with hot sauce as a second option for those who like a kick.
Sauces may seem like a small detail. At a counter built around fried food, though, the right dip can change the whole order.
So when the basket arrives, ask about the sauce choices. A little sass might be exactly what the meal needs.
Fresh From the Fryer or Ready to Grab
Speed is one reason the line keeps moving on busy weekends. Premade sandwiches wait in a self-serve warming cabinet for travelers in a hurry.
Patience pays off, though. The staff will make an order fresh for anyone who prefers it hot from the kitchen.
Fresh orders do not take long. One couple reported their tenderloins were ready in two or three minutes.
Regulars agree that fresh fried beats the warming tray. That tip applies to the sides as well as the sandwiches.
Families picking up several sandwiches at once have found the food affordable and fast. One group grabbed three tenderloins before heading home to northern Indiana.
The choice is yours. Grab and go if the schedule is tight, or wait a few minutes for something straight out of the fryer.
Kindness Behind the Counter
A car once broke down right outside this store. The staff let the stranded travelers wait inside for a couple of hours and checked on them to make sure they had what they needed.
Stories like that explain why friendly staff ranks among the most mentioned topics here. The crew is known for being kind, quick, and welcoming.
Employees have gone out of their way to make sure orders come out right. That extra attention stands out at a busy gas stop.
Some regulars say they feel like more than just customers. The counter workers greet people warmly even when the line is long.
Good food brings people in the first time. Friendly faces are a big reason they keep coming back.
In a world of rushed transactions, a little patience behind the counter goes a long way.
Big Portions, Small Bills
One cheerful fan summed it up neatly. You will waddle out for ten dollars.
Portions here are generous. Many people say a full tenderloin is enough without any sides at all.
Prices are described again and again as very reasonable. Years ago, a full sandwich ran about five dollars and a half was about three fifty.
Costs have changed since then, as costs do. A more recent order of a tenderloin, a corn dog, onion rings, and a fountain drink came to around fifteen dollars.
Not every bill felt worth it. One unhappy customer called a twenty-dollar visit a letdown.
For most, though, the value is clear. Plenty of food at a fair price is a big part of the appeal.
Why Weekends Get Crowded
Brown County draws weekend crowds, and State Road 46 carries much of that traffic. A popular food stop on that road was always going to get busy.
Many travelers make it a ritual. Some stop every year during their Brown County trip, while others call it their favorite stop on the drive home from Brown County State Park.
Motorcyclists find it too. One rider pulled in for gas and left with the tenderloin as a new go-to pit stop.
Word of mouth adds to the rush. Neighbors tell neighbors, and online lists keep sending curious eaters this way.
Some fans travel more than an hour just to eat here. Others treat it as a weekly reward.
Put all of that together, and the weekend lines start to make perfect sense.
Who Leaves Happiest
Families do well here. Kids tend to clean their plates of chicken tenders, and parents get a hearty sandwich without a sit-down restaurant price.
Road trippers are another happy group. The store covers fuel, snacks, a restroom break, and a real meal in one stop.
Fried food lovers will feel right at home. The menu leans heavily on breaded and battered favorites.
Those wanting a grilled option or a light salad may want to set expectations. The focus is clearly on the fryer.
Casual eaters who enjoy honest, filling food rather than fancy plates are the ideal crowd. It is good eating even beyond gas station standards.
In short, bring an appetite and leave the dress code at home.
Hours, Directions, and Timing Tips
Early risers are in luck. The doors open at 6 a.m.
Monday through Saturday and at 7 a.m. on Sunday.
Closing time is 10 p.m. every day of the week. That long window works for morning drives, lunch breaks, and evening trips home.
The store sits right on State Road 46 between Columbus and Nashville. Watch closely, since the building is easy to miss.
For the freshest food, ask the staff to fry your order to order. A short wait usually brings a hotter meal.
Weekends are the busiest time, given the Brown County crowds. A little extra patience helps during peak hours.
Updates are shared on the Gnaw Mart Facebook page. Checking there before a trip is a smart move.
Worth the Turn Signal
Some places earn their fame with big signs. This one earned it with a sandwich and a friendly hello.
The tenderloin leads the way, backed by seasoned fried vegetables, a playful sauce, and a crew that treats people well. Fair prices and big portions seal the deal.
It is not perfect for everyone. A few have left wishing for more, and the menu lives firmly in fried territory.
For most travelers, though, the stop delivers more than expected. Many leave already planning the next visit.
So the next time a Brown County weekend calls, keep an eye on State Road 46. A humble gas station in Gnaw Bone may become your new favorite tradition.
Just remember to slow down, because the best bite in the county is easy to drive past.
