Sultan Doner is a hidden gem, especially for those with gluten-free needs! My wife has gluten intolerance. Although the menu is not marked for GF, the owner was incredibly helpful in pointing out several menu options that are gluten-free.
Many of the kebabs are GF. And the additon of a Turkish coffee or pop drink, making it a great spot for a casual meal. It's also super convenient, located steps away from the baseball stadium and with easy access from the Roberto Clemente bridge.
While they don't explicitly advertise gluten-free options, the owner's help to identify meals for dietary restrictions was a big plus! Just be sure to ask about them when you order.
