The food is excellent! The vegan sour cream was the best I've ever had. I love that they have vegan and vegetarian options.

We had a great time. We came to Lava Hot Springs Riverside Inn for a getaway and night out and are already looking forward to our return. The food was great and the preparations done by the chef were excellent!

Was very excited to go here for our wedding anniversary. The Ahi tuna was good although I kept having to ask for more ginger. The service was below standards. I have been in the restaurant business for 20 years and was really expecting for the prices they charge a higher professionalism of staff. The server seemed as if she was too busy for us. And the ambiance was far from comfortable. I felt like we were sitting at the children's table at thanksgiving. The chef came out and spoke with 3 other separate patrons about their food but did not bother to stop although we made eye contact with him each time. And above all it was difficult to find. They really need to live up to their advertising and prices. ...sad.

The chef was the one to come out and greet us and confirm our reservation. He was very friendly and you could tell he cared about his customers. He also came out to other tables while they were dining to ask how things were. We were pleased with the service and the food was good. I did feel it was a bit overpriced for the portions served, but it was without a doubt the nicest restaurant we have found in Lava so that may be why. You can tell they only take on the amount of customers they can afford to without compromising service since it is a small place. When we entered, only about half of the tables were taken but the chef had told a family of four that there was a short wait time to be seated. The noise level was higher than we would have liked but it was due to a family with small children although it was amplified since the place is small.

This place was great. I look my boyfriend to lava hot springs for his birthday. He got the bison and I got the salmon. The bison was AMAZING. We loved it! The salmon was great it fell apart. I wasn’t the biggest fan of the sauce it came with but that was just personal preference because my boyfriend loved it. And can I just say their rolls were soooo good and addicting!!! The salad was phenomenal as well. I requested ahead of time that they bring out a slice of cake with a candle on it and they did! The only thing I can say a little negative about it was that it was kind of expensive for the amount of food you got. Otherwise this place is perfect! Compliments to the chef!

It was a great restaurant experience with wonderful food and an attentive wait staff. The chef came out to speak with us before and after the meal. Very impressive. I would definitely recommend the restaurant to a friend or anyone in Lava Hot Springs and the surrounding areas.

I mentioned to the waitress that this was a special occasion (my wife's birthday), we were in no rush and wanted to linger. She awkwardly greeted us with weird side-eye and mentioned that there would be others arriving later for dinner. At that time 1 other table was occupied, 9 were empty and no one else showed up.
The salad tasted the like the refrigerator. I ordered the bison sirloin, medium rare, ($38) and it was the consistency of shoe leather. I gave a piece to each family member, there we were like cows working their cud. The waitress asked how we were doing, I mentioned the toughness of the meat. Her quick reply seemed rehearsed, she'd obviously heard it before. After I paid the bill and signed the CC statement I noticed a discrepancy with the price of our appetizer. On the menu it was $16. On our bill it was $18. Feeling duped, I mentioned this to our server who brought it to the attention of the manager who also appeared to be the chef. A short, rotund gentleman appeared from the kitchen and proceed to "make it right" by correcting the $2 overcharge. After requesting an explanation, he said they revamped the appetizer selection and "forgot to change the price". I wish I'd followed up with a specific question on the date of the revamp... How many people were ripped off before me? The special occasion for our gathering was never mentioned. Cheapest glass of wine - $11. Cheapest bottle - $38.
I'll say this...cocktails were great, my kids fries were good and the dessert was ok. Everything else was terrible. I mean terrible. This place has a great web-site but it does not live up to its billing. I would never eat there again. Over-Rated!

When we go to Lava Hot Springs to soak, we look forward to eating at the Portneuf Grill & Lounge. Excellent choices for those who prefer healthy options. Food prepared well. We always order the scallops as an appetizer--deluxe. The fish entrees have been perfectly prepared. Fresh ingredients and beautiful presentation.

I was glad I made a reservation! As it was the off season they only had one cook on site. I really appreciated that they would rather have empty tables than let our meal suffer. The food was magnificent. I had vegan avocado tacos, and the home made vegan sour cream was phenomenal. I will definitely be returning the next time I'm in the area.

Very good for a higher end food experience. Waitress was very nice and positive. Not cheap but the quality of food, obviously a good chef is involved, is well worth the higher and appropriate pricing.

Hidden Gem! Portneuf Grille is located downstairs of the Riverside Hot Springs Inn. The bar was quaint and a fun place to get a cocktail. There is a happy hour from 4:30PM to 5:30PM. The service was attentive, we were greeted by the chef at he end of our meal which was a nice touch. There was a nice selection of vegetarian and vegan options and the chef was willing to accommodate to meet my dietary needs. 4 out of 5

The pumpkin pasta with sausage was excellent. We invited my daughter and her husband to dine with us and they both enjoyed their meal very much. The chocolate lemon cheesecake we had for dessert was the best cheesecake I have ever had.

Dined here over the weekend and it was pretty good. I had Butternut Squash soup as an app which was delightful, and the salmon was cooked perfectly. Only complaint was the sauce was overpoweringly sweet and my salmon was soaked in it. My boyfriend had the pork chop which also tasted great. Service was great, decor needs a little extra love but overall a good experience.

Great food and well worth the price. If I were to give any recommendation (not that it needs it) but the entrance could use a bit more flare. But besides that, it's the best food I've ever had!

This place has amazing food! We traveled two hours to partake of this special occasion meal. Birthday and Anniversary celebration. The filet mignon was melt in your mouth tender and flavor bursts throughout. The other menu items were outstanding as well. If you're ever in the neighborhood, this one is well worth the effort to get there!

Very friendly chef and waitress. The room is awful, green or brown indoor/outdoor carpet, old wood paneling, asbestos ceiling tiles. Very ugly and outdated. Despite their best efforts the food is off the mark; I have the poke appitizer, with fresh cucumbers, frozen tuna and something else? All soaked in soy sauce. The dessert was a lavender creme brulee, very heavy perfume tasing of lavender, way too heavy on the lavender, tasted like soap.

The menu itself was limited . Almost everything had fish or mushrooms which in our case limited us severely. It was $75 for two plates of food (including tip) but we only had water and no dessert, so it was the simplest thing we could have ordered. The food was really good, but we were still hungry. It was "outdoor seating" which means plastic yard chairs, rusty cans over the top of exposed sprinklers/tripping hazards, people with their dos, other people in the hot tub, broken pallets, a large trash bin, a cart with bags of dirty laundry, there was no where to look and have a nice view. Blue jeans and a nice shirt seems way over dressed. The food just didn't fit the environment. It was way too expensive for the environment as well.

We find this the ONLY place in our area where we are guaranteed to get a good meal that is well prepared. As usual our meal on the 4th of July was awesome. We are troubled, however, with certain indications of management problems (for example several draft beers were out of stock even on a holiday, dishwasher AWOL, etc) and hope that Riverside Hotel can correct issues such as these so that this restaurant continues to thrive. Looking forward to the next menu!
