    The dinner was such a delight. Derek was a great guide through the menu and the beverage program. The food was innovative and delicious. We started with pan seared scallops which were really nice, macadamia nut and parmesan sauce was a very tasty presentation. Then we dined on Pork Milanese and Chicken Carciofi. Both were well put together, presented, and very tasty. The proteins were accompanied by excellent side dishes that complimented each plate. The wine list, though not large, was expertly crafted to highlight wines that go well with the menu. Overall, it was a great experience and the next time we are in Lava Hot Springs we will be sure to visit again!

    Good food. We hade their two specials including the rack of lamb and the short rib. The short rib was fall off the bone tender and flavorful. The lamb was a bit overcooked and a little salty. Mashed potatoes were creamy and flavorful. Service was great and friendly.

    The menu is full of delicious options. They had several specials for Easter that sounded wonderful. My husband and I don’t do well with rich foods/sauces so opted for the cheeseburger. It was delicious, cooked perfectly and quite big. Fries were cooked perfectly as well. Both the servers we saw were very pleasant. It was Avery nice an Easter dinner.

    The entrees were surprisingly exceptional. Each of the dishes we selected was cooked to perfection and very flavorful. The staff was very friendly, helpful, and attentive. The dessert we tried was good, but did not blow us away like the entrees. The cocktails were very good and we enjoyed the bottle of wine that was suggested. An excellent place for a special dinner.
