I had visited Balaji vadapav at Mulund(w).The meal cost me at Rs.50 for me and my friend.It was really tasty vadapav I had eaten anywhere in Mulund. The food serving is also fast and they maintain cleanliness all over.
Besides vadapav there are other food items to choose from. However, the price for two is much for vada pav. The store is small because the crowd is too much inside it and you will find it difficult to order vada pav at evening or lunch time.
