This is my "go to " steakhouse. They have a gluten free menu with a decent selection. They will serve you some gluten free bread, which doesn't happen all that often in restaurants. Expect to spend $20 - $30 for your entree, but remember, they are serving you halibut or fillet Mignon.
I was staying at the Peppermill on a business trip. Very hard to find gluten-free at the casino. I ate at Ruby River twice that week. They were so helpful. The manager came to the table and spoke to me before they put in my order. With not just needing gluten free but also milk free it is a challenge! Rib were awesome!
I've eaten here twice without issue. Let the staff know if you're celiac and the manager will come talk to you and then go to the kitchen staff and make sure your food is safe. They will cook your food on a clean pan or on aluminum foil. It's a little bland though.
We were happy to find one more GF option for dining out! Ruby River Steakhouse has a good assortment of options on their gluten free menu, including dessert! The food was very good and plentiful. Everyone was happy with their choices. The staff was friendly and the service was great. We'll be back!
