The concept behind this small kiosk outside big retail stores is really good. Read about the founders and how they expanded their businesses here. That said, I must say the taste of the burger is not superb. The main problem is that the bun is not fresh and soft! That takes away the fun of eating a really yummy burger. Also, the bun is small and a lot of sauces +cutlet+onions are crammed in between the two small buns, making the burger look larger (than life :P) !
All said and done, the concept is innovative and maybe the place is worth trying out once. I wouldn't go back there, for sure.
Location: Outside Ratnadeep super market, Somajiguda (and at many such places in the city)
