Walking from Penn Station over to Madison Ave, I stumbled upon Mandoo around 1pm. The place was packed and the service was very polite and fast. I had an absolutely delicious dumpling soup and a beer. Tab came to 13 bucks. I was stuffed and satiated in less than 20 minutes. Most other folks seemed to be downing bibimbob or something very interesting looking and satisfying in hot pots that goes for 8.99.
