Yeah, tell me about it! There is one on Britannia and Creditview. A must reccommend for all.
8 oz of thick, juicy, grilled, 100% angus beef and that too halal? 
I always used to pass by and just the name kind of turned me off. but after my friend insinuated me to drop by there, I have been there twice already. (Without him offcourse. ;-)) Lol.
As for the Karachi boy fast food:
Never heard of it. Where is it? and like Muzna asked: what is on the menu?
