Very small stall on CST Station. They say they have trademarked "Frankie". Don't know weather that's true or not but they do put a lot of chat masala in it. Although they don't actually have seating arrangements, the station has a small seating facility that's just next to it. I usually have egg and veg frankie. Nice to try it once. They also sell cold drinks at surprisingly cheaper prices. Such as i got a glass of thumbs up for 10 bucks. Awesome during summer.
