I would say the are OK with accommodating with Gluten and dairy free. I was able to get the chicken kabobs (grilled brochettes of chicken breast marinated in Moroccan herbs and spices) with rice and hummus (with an Ener-G roll). I've also had the meatballs with rice at Tangierine Cafe, but I preferred Restaurant Marrakesh.
I haven't been since they made some vendor changes, but I imagine you should still be able to get the same dish or something similar. I remember having some other options (including fish) too. The chicken was pretty delicious, and I would definitely get it again.
They also have really good hummus!
