The food is fantastic here. Both the chef and the waitress were very attentive to our needs. The ambiance was quaint, unhurried and quiet. We will definitely be back again.

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 Very ugly and outdated.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!

Casual elegance fit for a foodie! Quaint little restaurant at the Riverside Inn in the charming little village of Lava Hot Springs. Who would've thought one could find world class food and cocktails here? Thanks to the expertise of the culinary staff led by Chef Alonzo, fine dining is possible in this casual atmosphere. And don't forget the live music every Thursday night featuring distinguished musicians from around the country!

Food is hit and miss. Pork chop was amazing, and clams were pretty good, but egg noodle primavera was disappointing. Thick, alfredo-like sauce - primavera should be light. Our service was terrible, waited 20 minutes for drinks and the restaurant was not at capacity. Server took plates away before we were finished, appetizer came out before our drinks arrived, server took menus away before we were ready to order. It's hard to feel like we were being rushed when everything took so long, yet somehow she made us feel hurried and forgotten at the same time. For the higher price point, I would expect fine-dining quality service.

I enjoyed our dinner night out. Service was very good and the food was very delicious! Live music kept us entertained. The only thing I did not really care for was the "looks of the room" (ambience)- very dingy; needs a woman's touch and some friendly/ clean looking colors to brighten up the room. Maybe start by placing fresh cut flowers on the tables to make it all look a bit more inviting and friendly. Maybe use plates with a colored trim etc. But all the staff was super friendly and accommodating. They made sure we were taken care of in the best way possible.

This was our second year to visit and stay at Riverside Inn and have dinner at Portneuf Grill.
A great stop on an icy, cold winter day/night. Everything you need, including private hot tubs, in one place. Friendly/helpful staff at the Inn.
The cook and waitstaff at the Grill were very welcoming. Enjoyable live music.
The meals were delicious, nicely prepared and served. The flaming dessert was outstanding!
Will be back again next year!

Excellent food and service. We enjoyed our meal very much and plan to return. Had salmon with a lemon cream sauce, delectable and perfectly cooked, as were the tender green beans as a side. The tabouleh complemented the salmon well. My husband had perfectly cooked scallops which were delicious. We highly recommend eating here. Such a find! Service was friendly and efficient too. Dining room was quiet, but a bit chilly. We were staying at the hotel, so I could grab my sweater from my room. Thanks for a lovely evening and great meal,

Alanzo was the employee of the month and much deserved. He went above and beyond for us. I called to say I was running late to my reservation, they were closing soon after, so he took my orders and had everything ready when we arrived. He didn't make us take it to our room like we anticipated, but set us up at the bar top. He had even stayed an hour later than he was supposed to just so we didn't feel rushed to eat our food. He was great to converse with. The food was amazing, so many pairings that would seem rather odd tasted amazing! It was a great experience and I will most definitely be dining there when I return to lava hot springs.
