Food was ok. Atmosphere a bit cold/industrial but also ok. Not nice at all was the guy on the counter taking the order, since he acted so bored and bothered that it wasn't friendly at all.

If you are a lover of hot dogs or smoked sausage then you will love their Smoked Bison Bratwurst. It's paired with simple grilled onions and green peppers. Subtle smoky flavor, juicy, great flavor served on a warm bun. Better than any state fair beef or chicken sausage I have ever eaten. I wasnt even hungry and wanted more. Someone find out the vendor who supplies that tasty treat.

Our family of four had a great experience at the Terrace Grill in Yellowstone National Park. The restaurant was very clean with plenty of spacious indoor seating. Service was excellent, the food was yummy, and prices were very reasonable for being inside the park. The kids loved that their meals came in a Yellowstone bus cutout—such a fun idea! We also recommend their coffee, which was surprisingly good. We finished off with ice cream, the perfect treat after a day of exploring. A great stop in the park with good food, friendly service, and a welcoming atmosphere.

So fast we barely found a place to sit and it was ready. Typical prices that you will find in the park.

The hamburger at the grille was aweful. I mean, just gross. Just don't eat there. It was disgusting. You'll end up throwing up or throwing out 99% of the grossest hamburger ever! Aweful. Gross. Disgusting.

We stopped here after watching wild life @ Lamar Valley. The bacon, egg, cheese breakfast sandwiches were delicious with crispy bacon. The hash browns were crispy. The cold brew coffee was pretty good compared to other places in the area.

No taste. Party of 5 and all got something different. No taste whatsoever in anything we ordered.. also, it is pricey. Should have known when we walked in and all tables were unoccupied.

Got 2 orders of Avocado Toast, it took 25 minutes to come to us. The server Andrew, wasn’t that kind to us. They didn’t refill our water until we got the check and had to ask. They charged us for egg toppings we never got. Wasn’t a fun morning there. $41 for 2 toast is crazy.

After spending some time in the park, this place was exactly what I needed for a quick bite. Prices felt pretty normal coming from California, the service was straightforward, and the menu was surprisingly big for what’s basically a fast-food spot.

They’ve got Coke, and I couldn’t resist finishing with a scoop of ice cream — honestly, it hit the spot.

Is it five-star dining? Of course not. But compared to everything else I’ve seen in the park in this category, it’s definitely a step up.

The best part? I had my order in hand in about 5 minutes, which meant I could eat, recharge, and get back on the road without losing half the day.

Sometimes, that’s all you need.

Decent quick diner style food. It’s the only quick option in this area of Yellowstone.

We stopped after a long day in Yellowstone and ordered a (100% beef) hotdog. It was absolutely inedible. It had a brownish/greenish look at the end, as hungry as we were, took a bite anyway. Tasted like a vienna sausage with the texture being mushy. Spit that bite out and threw away. The hamburger was not much better. There was only pump style ketchup with no container to put it in. Worst money I spent while in Montana.

We stopped last night after visiting Yellowstone National Park. The burgers tasted worse than cafeteria food with the cheese barely melted on. The supposedly 100% beef hotdog tasted just like Vienna sausage with a dark brown hue. The only half decent item were the fries.
