This row of street food stalls is located across the street from Flora Fountain in Mumbai. They don’t all sell Vada Pav, but the most popular one does. (Alternative spellings: wada pav, vada paav, or vada pao)
FYI: Vada Pav is a delicious deep-fried, spiced potato ball served as a sandwich on a fluffy dinner roll style bun. It’s a Maharashtra specialty. There’s a video below if you’d like to see how they’re made or to make your own.
