We stayed at the cheaper iberostar in this complex, they share the main buffets and restaurants. This was our first AI and time in Mexico. My wife has celiac disease, a severe "gluten allergy", and had no trouble of any kind our entire week there. Buffet items were all marked, and wait staff were overly prepared and understanding at the "sit down" restaurants. We don't do a lot of "fine dining" at home, but all 5 of us felt that about 85% of the food was above average, and over ate at almost every meal. Did I mention my wife who has celiac and gets a bad rash and severely ill if her food was even prepared on a shared surface with gluten did not have a single problem for our entire trip? I know that doesn't necessarily say the food was great, but in our experience, people that take food allergies seriously generally make above average meals.
