With lots of soup and salad options, I thought there would be ample gluten free choices. Unfortunately the server at the salad bar had some strange answers to my questions. When I asked about soups, he said all vegan soups were gluten free. I asked why it corresponded to vegan and he didn't know. When I pointed out the tomato soup had pasta he said they would make it without. I chose a salad and asked about the dressing. He didn't know and was reluctant to go check. He wanted me to order the herb vinaigrette. I asked him to please check and he quickly came back announcing it had mayo therefore was not. I pointed out that mayo rarely has gluten and that seemed odd. So I chose another salad. "No, that one has sugar." I pointed out that sugar is not gluten. He was growing impatient with me and clearly was guessing about something he knew nothing about. We left. I was disappointed and embarrassed because my friend thought she made a great choice for us. I looked online later and saw that other GF diners have had similar experiences at Cafe Zupas.
