Roberto`s has become another must visit when we come to Mammoth. The food is excellent. Last visit I had a chicken tostada. The lettuce was fresh, it had a ton of chicken, and the shell was crisp. My son ordered a bean burrito off of the kid`s meal & it was enormous. My husband and I enjoy the Cadillac margaritas. You can actually taste the tequila vs more watered down versions elsewhere. We appreciated being seated on this visit because we walked in about 10 minutes before closing. The only negatives I have are that I feel it is a bit pricey & lacking a bit in customer service. We don't necessarily feel like valued customers. We will definitely return for the food.
