My little sis is getting married in Kolkata in December. We are all arriving just a few days before the wedding, which is in a hotel with a mixed Indian/Western buffet as the groom is European while the bride is Indian. Bride and groom have friends from abroad who will be coming to Kolkata to attend the wedding. Because there will not be much of a chance for them to all catch up during the wedding, we were hoping to organise a pre-wedding informal meal. It could be lunch or dinner, preferably somewhere central, preferably traditional Bengali cuisine, which is difficult to get anywhere else. I looked up Kewpie's, 6 Ballygunge Place and Oh Calcutta online and it seems as if you pay a hefty price for small portions. Any suggestions? It would be for a group of 15-20 people.
