I went last Saturday and really enjoyed. It's strange being on the other side of a HUGE wall that (barely) hides a HUGE villa, but not that much different from being in Retiro. And the Koreatown side is nice with interesting markets selling all sorts of Barrio chino and Liniers- type products for much cheaper than in the aforementioned places!! We went to a restaurant on a side street. It doesn't say the name out from but it's at Saraza 2135 (you must ring the bell) and the official name is Hang Gu Kuan. It was $140 per person not including drinks. It seemed a bit dingy and was just off the main street but was full of Koreans, we were the only foreigners in there. None of the servers/ staff we saw were Koreans but all the tables were filled with huge groups of Koreans so it seemed like a good decision. And most of the food was great. Of course there were some plates that we had to ask ourselves why they might have served this (some weird potato salad thing for example) but the meat was yummmmmy!!! A++!
