We have lots of "American" restaurants here in Abu Dhabi. Fuddruckers, McDonald's, Hardee's, Burger King, Dairy Queen, Starbucks, Seattle's Best, Subway, Gloria Jean's, KFC, Pizza Hut, TGI Fridays, Chili's, Basking Robbins, Dunkin Donuts, Benihanna's, and probably a few I am forgetting. A short drive to Dubai and you can have; Taco Bell, Macaroni Grill, Ruby Tuesdays, Johnny Rockets, Tony Roma's, and more.
Each one of them has a "local" twist on how they serve the American menu with inevitably at least one variation on the menu. I am sure this is common around the world with these popular chains. I remember in Ecuador that at Kentucky Fried Chicken, extra crispy or regular came with a side of rice and plantains!
I'm not a big fan of fast food, and I haven't eaten at all of the above but a few things I've noticed.
Starbucks drink menu has many less choices.
McDonald's, Burger King, Subway, Hardees, KFC, and yes Dairy Queen delivers!!!!
Subways meats are all turkey or beef products.
Tony Roma's ribs are not baby backs, they are beef short ribs.
The pizza here is not even close, from what I have heard.
Baskin Robbins serves a local saffron icecream that is amazing!
The best has got to be McDonald's grilled chicken wrapped in Arabic flat bread.
A picture is worth a thousand words!!
