Need suggestions. Want to take my parents somewhere nice to eat.

We are proper bheto bangali and baire khawa always means Arsalan Biryani and chicken chaap and experimentation means Haji/Shiraj biryani. I want to take them to some place different. Few considerations to be taken is:

  1. 6 Ballygunje place is rejected 2. jhol jhol na hole hoye na to "Peter cat er dry bhaat with shukno kabab is bad". 3. I was thinking of BBQ Nation or ITC/Marriot Buffet but they have said "eitukini khabo gadi gadi taka jabe"

Most likely I will take them to some buffet but if you guys have some better suggestions I am all ears.
