Wonderful food. One of the best pork chops I’ve ever had - very nicely seasoned and served with a baked pear covered with nuts and goat cheese.

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.

A great find. Cozy little B&B. Alonzo the chef was great. Didn’t think we would find a meal like that in Lava. We will be back.

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!

Salmon was good. Bread was delicious. New York strip was tough and tasted odd. Too pricy.

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.
