k-town open Sunday for late lunch, hopefully with tripe soup??
Every Korean restaurant will be open. EVERY one. In fact, I believe all of the ones in that area are open 24 hours. I'm not sure which ones will have tripe soup, but I'm guessing that Gam Mee Ok on 32nd and Woo Chon on 36th are likely candidates. I've had a nice cold cut plate including intestine and liver at Gam Mee Ok, and Woo Chon has an extensive and interesting menu.
