Flor de Lotus has lots of options for vegans, including salads and hot dishes. I've asked two different attendants and they assured me that NONE of the dishes are made with milk, not even desserts (!), great for both vegans and lactose intolerants. It's generally (but I haven't asked yet) also egg free, so the only thing for us to avoid are the dishes with fish, easy to identify. Don't forget to try the "inhame palha" (fried yam) with guacamole.
