Love this place -- have never gotten gluten'd here, AND the pizza tastes amazing.
The simple side salad was also safe, BUT the server wasn't attentive and brought my side salad *with croutons* the first time. Rectified it, though.
So, my advice is to do the usual thing and mention the gluten-free necessity at least 2 times during the ordering process (3 is better; people just don't care sufficiently for other human beings' health unless reminded).
