You should try Kumar's Dosa, no they are not crepes, in NYC out of a food cart at Washington Square Park South and Sullivan Street.  There's  lot of simple vegetarian food that comes out of India and can be veganised without much trouble.  Kumar does not use any dairy at all.  If you don't mind dairy then you should eat at the Saravana's in NYC where you can try a (clarified butter) Ghee Roast Dosa.
