Not very safe for celiac.
Yes, they have gluten-free options and it’s a nice spot for a meal. BUT be aware that the kitchen is small and there are at least 3-4 people who communicate/cook/serve your order leaving lots of room for mistakes. I ordered an omelette with super-clear direction on how to prepare it and it arrived with fried, unsafe hashbrowns. I had to send the meal back and stick with yogurt and fruit. Be careful.
