Hi and welcome to P-town! I'm new to this site but I've been living in Pyeongchon for almost 6 years.
The foreign run or foreign friendly bars I mostly like to go to are the Dug Out off Hagwon-ga and Fongs behind Uiwang Art Street. They've goth got great owners and clientele.
As for restaurants, my local favorites would be the Italian at the top of Acro Towers, the Indian/Nepali in Anyang downtown area, and there is a lamb galbi and kebab place in Beomgye that I like, and it's name translates to "the Silence of the Lambs!' Delicious, ft ft ft ft ft ft!
Does anyone have a favorite regular galbi or samgyeopsal place? There are loads of great ones around here, but I'm always on the lookout for new good ones.
