Curry is a delicious foods, but curry in India is really sloppy.
I actually love Middle Eastern foods better than Indian foods or Pakistani foods, but Indian foods are not bad at all.
However, I visited India last summer and I puked because they were so unclean.

I hope India better take care of sanitary problem even more.

There's sanitary problems everywhere, it just depends what region of the country you go to.

What about Bangladeshi curry? Some of the world's most popular curry dishes are Bangladeshi, like the Chicken Tikka Masala.

Isn't Chicken Tikka Masala the UKs unoffical national dish or something like that?

It was developed by immigrant Bangladeshi chefs in the UK some decades ago, so you could say its a British-Bangladeshi curry dish.

It tastes yummy
