A fun, delicious experience! The servers were all very polite and accommodating- we had a couple of people with celiac and other dietary restrictions and the staff handled it well! The cheese bread was gluten free and delicious, and all the meats we had were very yummy. A suggestion- be patient for the doneness of your preference. They had a variety going around so you don't need to "suffer" through one you don't enjoy. Buffet was just okay; some of the food wasn't very good, but no one goes to a Brazilian steak house for the buffet. I would definitely go to Rioz again!
