I was at the Cactus Club last night for dinner. While they opt for a 'removal' strategy (ie burger without bun, salad without croutons, rice bowl without sauce), they were able to accommodate gluten free, and the wait staff was quite knowledgeable. They are also in the process of printing 'gluten-friendly' menus, and you can already access them online. I had checked the menu beforehand, so I packed myself a bun and had an excellent burger, with a fancy side salad. They did have a few chicken and steak options available gluten free as well. Not too shabby.
