29 at Kemps Corner Mumbai, as the name suggests serves different food cuisine from 29 states of India . You can go with recommended list on your table which lists 1 special dish from each state . It has a bit different Menu usually not similar to other restaurants that we see.
Thanks to Narayan Sahu for sending the update.
