I'm not a vegetarian, but my best friend is. You can get a veggie burger in any of the parks, but not at every CS location. She likes Columbia Harbor House in the MK and the veggie sandwich at Main Street Bakery. I wasn't crazy about the seasonal Mexican CS across from Pirates (can't remember the name) but she thought the veggie tacos were really good. Epcot has a lot of great CS for vegetarians, including the CS in the Morrocan Pavilion. There is a new Italian place opening in the late summer/early fall that "may" have a CS window that you could check out. As you might expect, there's almost nothing at the CS in Germany. France and Norway have sandwiches and quiche. DHS and AK are a little more difficult. At DHS you can get veggie sandwiches at Starring Rolls. Pizza Planet has cheese pizza, but it's just so-so. To be honest, I thought AK had very little for vegetarians.
