Korean Fried Chicken in London
Looks like a variant of gan pong ki (phonetic translation, unlikely to be 100% identical in all places), a dry fried chicken with a soy garlic sauce that's typical in Korean-Chinese places.
Ate at You Me in New Malden with a couple of hounds a while ago and admittedly we weren't particularly impressed with the Korean-Korean items, but the menu had a whole bunch of Chinese-Korean stuff, which we didn't try, so that might be a place to start exploring (rather than a sure bet).
Woojink on Tottenham Court Road didn't particularly impress with the bindaeddok (mung bean pancake) or dolsot bibimbap (variety of vegetables and meat with rice in a hot stone pot), but again there was a number of Korean-Chinese items on their menu. Which made me wonder if I wasn't playing to their strengths in a more specialised version of Korean cusine or if the general execution was just so-so.
Will be especially grateful if other hounds can chime in on more of the Korean-Chinese aspects of these menus or at other places.
There are some taco trucks in LA that use Kimchi as one of their condiments. NYT did an article on them, and I'm sure a quick google search will turn it up.
In general, in Korea anyways, the Korean-Chinese places specialize in specific dishes and don't do the "usual" Korean restaurant stuff (and by "usual", I mean the generic stuff you see in a Korean restaurant outside of Korea). That might be one reason why the place on TCR didn't impress you. Though I do think of dolsot bibimbap as the safety choice--the one thing restaurants can't possibly mess up, because there isn't much to--and so it's kind of strange to hear that it wasn't good. If it's a Korean Chinese place, might be a better idea to stick with korean chinese classics--jjajiangmyun (http://en.wikipedia.org/wiki/Jajangmyeon), jjambbong (http://www.flickr.com/photos/30255546@N02/3343370918/), etc.
On the topic of chicken dishes--it's been a while since I've had chicken (am fake vegetarian, eating fish but lactose intolerant), but as far as Korean dishes go, sam-gye-tang (http://en.wikipedia.org/wiki/Samgyetang) had been my favorite. It's kind of like hainanese chicken rice, except the rice is cooked inside the chicken and there's soup and ginseng and other goodies involved. Last time I had it was summer about eight years ago, when my family went on vacation to the mountains up East and stayed in a farmer's extra room. The wife killed the chicken right before us, which was a shock then to this city girl, and I think I had put on some feeble affectations to my parents about not killing animals, which was reined in by hunger and appetite when the soup came around. I can't say I don't miss it on this cold, wet London night.
I can't comment specifically though, because I haven't been to any Korean restaurants in London...
