Called before arriving to confirm that they have gluten free options and the gentleman on the phone was very kind and confirmed that they can let the kitchen know about a food allergy. However, when we arrived and asked about the gluten free options, the wait staff looked at us in confusion.
The older gentleman with glasses who took our order was very rude and impatient. He hovered over one of us, tapping his pen, after we kindly told him twice that we need more time to review the menu. When we asked if we could substitute black beans instead of refried beans he had no idea what we were asking for and then angrily responded by saying it comes with "regular beans!".
The other wait staff were more friendly, but the service overall was not good. Chicken was barely seasoned. We've been to many authentic Mexican restaurants, but not a good experience for our first time here.
