I have been asked by some co-workers to find an "ethnic" spot for lunch. "Ethnic" here, means, not burger and fries, so French is good. I am looking for mid-priced, close to 17th and Arch. One problem is that one person is a vegan (tough). Lunch is the key word because a few places are closed. Any help would be greatly appreciated. I've already suggested Brasserie Perrier and Pasion, but for a Vegan they are not too good.
