Probably Masalawala & Sons, which is specifically supposed to have Kolkata-style food, but the prices are ridiculous. Otherwise you might have better luck in Edison, NJ.

Masalawala and Jalsa in Brooklyn.

This is a long shot but DCUM often delivers! I’m heading to Manhattan and would love to find a restaurant that offers Bengali food. Not Bangladeshi but West Bengal. Even a place like Bethesda’s Passage to India, which offers a few items, would be great. Anyone have suggestions?!
