if i had only 20 rs in my pocket, i would go to R.K vadapau, located at vijay char rasta, ahmedabad. u get a regular vadapau in 7 rs and a butter vada pau in 9 rs.served with tomato sauce and green chutney, it is more than filling and chilli and mouth watering and if u have two, u cant feel hungry till dinner for sure.anytime you go there, you can never find less than twenty people waiting there in a queue.its heaven on the earth for sure.
