Incase you missed it, treat yourself to 8 restaurants under one roof.

The Park Hotel, Kolkata.
57A, Park Street, Park Street
Anandilal Poddar Sarani, Kolkata.

There are 8 restaurants inside the Park Hotel each specializing in different cuisines and taste:
-Zen
-Saffron
-Tantra
-Someplace Else
-The Atrium Cafe
-Roxy
-Aqua
-The Street

I suggest that you go there and check out just one of these restaurants.
