The best thing we know about China is its cuisine. Chinese foods are very popular in many parts of India. There are lots of restaurants serving Chinese cuisine here. And if you ask us Calcuttans (Kolkatans), then we know more about Chinese cuisine then any Chinese!
Actually there is a large population of Chinese in Kolkata, and their main businesses are leather products and restaurants. We have lots of Chinese restaurants as well as multi-cuisine restaurants also serving Chinese everywhere in Kolkata. There is also a place called Chinatown in Tangra, Kolkata which is full of may be some 100 or more Chinese restaurants, both big & small!! One of my clients is a Chinese (now Indian citizen), probably a Han Chinese as his name starts with Han, he also runs a Chinese restaurant. He goes to China once in 2-3 years to meet his relatives there. I once asked him if the Chinese foods served here are the same as in China, he said yes; they are authentic Chinese.
We even serve Chinese in occasions like marriage ceremony, birthday celebrations also along with different Indian cuisine. Note that most Chinese restaurants are run by Indians all over India, and biggest of them is the restaurant chain "Mainland China" run by a Bengali.
Chinese foods are very popular as street foods also, while restaurants serve hundreds of different dishes, Chinese street foods are mostly limited to variants of noodles/chowmein,
momo (dumplings), fried rice, & chicken items like chili chicken or
schezwan chicken, etc. (Names might differ). We mostly stick to dishes made with noodles, rice, chicken, prawn, & fish, we don't venture into other kind of Chinese foods!
