Dude relax. Looks like you're rearing up your behind for a fight
This scenario has been seen here many times before. The menu and selection changes to more casual with (relatively) more reasonable prices or - as is the norm, the patrons stop patronizing the place, and the place closes. Simple as that. Dhaka's skyview restaurants from the early 90's are a great example (Sky Room, White House etc.). Maybe @
BDforever can vouch if he wasn't too young back then.
My point is - as the clientele gets more mature by having more options - they stop paying Tk.1000 for a simple club sandwich, no matter how nice the place.
