This thread is somewhat tongue-in-cheek, for it's not as if I'd like to witness even more chains flood the market. However, if they aren't here yet, I don't reckon that they will soon transform into the hares that Starbucks and Subway have become.
In any event, there are a few chains from around the world that I'd actually eat at if they existed in New York City (in no real order):
1) 老鄉村 (老乡村) Lǎo Xiāng Cūn- China, specializing in Hunanese food. Watch out for the dizzyingly large number of garlic cloves that make themselves home in many of the mains.
1) Matsuya - Japan, budget Japanese comfort food, often 24 hours.
1) MOS Burger - Japan, hamburgers...and "naan." But hamburgers are the clear favorite.
1) Nando's - South Africa, known for flame-grilled chicken with peri-peri sauce. Their minty peas were swell too.
1) School Food - the RoK, but this is one I haven't yet tried. I stumbled upon one in Jakarta (in case you're heading to or in the city, it's by Mega Kuningan), but beef bacon just wouldn't cut it. Anyway, Korean food is usually good, so maybe one day.
1) I can't remember the name, but it was a fast food (hamburgers) place painted blue and white in Bloomington, MN. That wasn't the only one, but they had a particularly worthy burger for this list.
