There's an excellent new street cart in Greenwich Village on the South side of Washington Park near MacDougl. It's a dosa cart called NY Dosas. The very friendly cook is from the Dosa Hut in Flushing who became sick of working in a hot kitchen and wanted to be outside.
A small but complete menu of Indian Vegetarian appetizers(lentil donuts and steamed cakes) and dosas. I haven't tried that many dosas but these are best I've ever tried. They're prepared freshly with great care and they're not leaden at all as others. I think it's my favorite find of the summer.
He'll be there 11:30-6 everyday but Sunday.
