I am sure it varies by what place in that area we are talking about, but let’s say a general sample. Any common dishes that an uncultured desi like me would know about? I already know about Chum Chum.
I am quite surprised that there are tens of thousands of bengalis in Karachi, yet I never saw a Bengali restaurant there. Or maybe I didn’t look hard enough.
You've probably eaten bengali influenced food without realising it as most indian restaurants (at least those in england are anyway) are run by chefs of bengali ethnicity.
