First it was the vegetarians. Then it was the pro-protein, anti-carb crowd. Then the vegans sprouted up on every corner. And now it's all about gluten-free. (FYI gluten is a substance present in cereal grains like wheat that creates the elastic texture of dough, and a growing number of people are developing an allergy to it.) So what's a gluten-free gourmand to do? Surrender to a life of boring steamed vegetables and a few pieces of fruit? Not even close. Restaurants are getting creative with everything from gluten-free pizzas and gluten-free Thai food to gluten-free cupcakes and gluten-free beer. Here are 12 places, including more than a few surprises, for delicious gluten-free dining in LA and OC.
