You can check out Cafe Wink it's gorgeous and of course you have your good old Bercos that dishes out a great fare!
Khanna Tandoori Junction in Krishna Nagar!
So there's a really great Chinese van just aside of the Leela Ambience hotel in service lane named Garden Hut. The Chinese there is really good and you must try their spring rolls. They are my personal favourite.
For the best Chinese cuisine in East Delhi, I would suggest you to visit Omg Chinese which is in Mayur Vihar Phase 3 and The Fat Mermaid in Anand Vihar.
