This looks very much like a popular US restaurant chain called Chick-fil-A which is also a chicken specific food outlet, and the menu is surprisingly almost the same!
The only difference is they are a strick conservative Christian restaurant, they do not serve beef and are closed on religious days, but they also have the same chicken sandwich, wraps, nuggets and so on as Al Baik.
Like Al Baik, Chick-fil-A also gets huge crowds at times. I do not go, but it is well known in my area because the line of cars going to lunch or dinner at Chick-fil-A can get very long, I've been caught in the traffic.
Glad you have a place you like, and there is no question that American tourists would like Al Baik. My brother eats a lot of chicken (but no pork - but he loves halal and what is called "Mediterranean food" which really means Turk, Arab, Lebanese here in my area and not Greek), I know he would love your restaurant, are tourists allowed to go?
