Food was amazing. Wanted to eat light and the appetizers sounded so good we ordered 4 and could have filled up with 2. A lot of food for the price. For such a small town, excellent service and daring food - Breakfast was amazing - a pastry chef that makes the most amazing cinnamon croissants. Dreamt about them!!

Not a lot of choices in Lava, this one was excellent for dinner. We ate in the bar area, service was excellent and reasonable.

My boyfriend and I had a nice get away weekend in Lava Hot Springs. We were going to go soak at the hot pools later on in the evening and decided to eat first so we didn't have to change again for dinner. We did not have reservations (fairly early Saturday evening), and they were readily able to get us... More

Though small and simple looking, this popular restaurant has a surprisingly wide menu from soup to bison. Nearly every table was taken on the Saturday night of our visit. Our group tried the salmon, bison, elk, and chicken and these entrees were delicious and reasonably priced. I appreciated that they post their menu online too, as that helped in the... More

We dined here on a Wednesday in the summer. We were staying at the Riverside Hot Springs Inn and received a credit good for 2 nice glasses of wine or beers as part of our stay. Our meals were very tasty and they were able to accommodate some dietary restrictions. We were traveling from SLC to Yellowstone NP and decided... More

We loved our dinners. They were cooked to perfection according to our request and with much flavor! I had the New York Steak with mashed potatoes and green beans and my husband had the grilled chicken with rice. We both loved our choices and would go back again. The food was so flavorful.

This has been the least desirable restaurant that I have visited in this town. I ordered the Oyster Burger and my husband order the Elk Steak. The burger was not bad, but not particularly good and certain did not warrant the price. My husbands steak was smothered in a blueberry sauce, The flavor wasn't bad, but the the seeds were... More

We dined twice, the food was great, the mixed drink (Pomegranate Martini) very delicious. This restaurant has the flare of an upscale restaurant without being pretentious. We were greeted by the chefs for both dinner and breakfast, which was a nice touch. The salmon was excellent, tasty and tender. We were impressed with the mouth-watering pastry breakfast buffet, they have... More
