We're going to be spending about two weeks in Kolkata (Calcutta, for those not into the Indianized name) in January (soon!). As it is our second extended stay there (work for me, pleasure for my s.o.), we are looking for additional diversions, and one that would be particularly appealing would be some lessons in Bengali (or Indian generally) cooking. I cannot find anything by standard online searches, so I appeal to the readers of this board -- any ideas of specific places to go for classes or where to look? We'd love to hear about anything, from a one-time class to a week-long series. Thanks.
