Vegetarian, Gluten-Free, and Vegan are on the menu, but the same kitchen also prepares what you avoid, so cross-contamination is possible. Tell staff what you react to, and ask how your dish is prepared before you order.
SOL Bar & Grill is the hotel restaurant at the Four Points by Sheraton Tucson Airport, serving American food with a Southwestern touch. The venue says it offers gluten-free, vegan and vegetarian options, subject to change, but its printed menu marks no dish. Tell your server about your allergy; the kitchen has the final word.
