I was not aware Red Robin had gluten free buns. I told the waiter this was a gf order and when he brought my guacamole burger on a bun I was shocked. He then told me it was a gf bun. First time I have eaten a hamburger on a bun in 2 1/2 years & it was amazing! I asked him to find out the name of the bakery & it is French Meadow Bakery from.Eagan, MN. The fries also were down in separate.fryer, gf. Loved the meal & waiter.was.excellent.
