Unlimited Vegetables. 

Typical restaurant sides like pasta, cous cous, and french fries (which typically share a fryer with items breaded with flour) are gluten-free nightmares, but restaurants can easily substitute them for a side of steamed or sautéed veggies. When it comes to vegetables, anything goes! Simply ask your waiter for a side of veggies sautéed in a little olive oil and garlic, and enjoy whatever seasonal vegetables they have in the kitchen.
