The menu changes all the time. I had first gone to a, PF Changs in California and they had a huge selection of gluten free meals on very large portions. I have gone to a few local restaurants and the menu changes all the time. Usually there are now a few things on the menu that are both gluten and dairy free, but sometimes just one. I was actually told if you call a few days in advance they can "usually make something". The portions are still big, but personally, I would like a little more freedom in when I eat, without planning so far in advance for still limited choices.
