Seasons 52 was thoughtful enough to make a separate vegan menu, you just have to ask for it. I've always been sad that they don't make any of their flatbreads vegan, especially since they obviously want to make us feel welcome, but I saw a comment somewhere that will if you ask? I don't know if this is true, but the food they do offer is really delcious. They have a fruit cup dessert if you want something sweet after your meal. It's a little on the fancier side, and you should probably make a reservation during season or peak hours.

Cons: can be pricey for some budgets, no vegan flatbread
