What are the parameters that you will use to rate a 5-star hotel. Since they are in the hospitality business the specialize in the comfort of their guests and ensure that the facilities that they provide are world class. I have never got a chance to stay here as I don't require (since I belong to Kolkata) but I have always wondered how it would be to stay here for a night.
ITC Sonar has all the merits of a 5-star hotel - a nice facade, big lobby, courteous staff and lounges and restaurants serving different cuisines for people with different tastes. However, since this building was built a while back it is not as modern as the JW Marriott which has an opulent lobby which catapults you in a different world altogether. ITC is trying to change that with the new building which they are constructing adjacent to the current building and it is going to be huge. From the looks of it, it is going to be a magnificent building and will become a landmark for Kolkata. Keep waiting for next updates
