Kunj Vihar is a decent little place in Thane that serves an pretty good street food. The restaurant has simple ambience and decor. They are least bit fancy and have just the basic furniture.
The staff here is super efficient and knows the menu at the back of their hands. They will give you a list of recommendations according to your preference and I will suggest that you go with their recommendation you wont be disappointed.
Some of the popular dishes here are Samosa Pav, Wada Pav and Misal Pav. A meal for two will not cost your more than Rs 400 which pretty reasonable these days.
