Simhaksan Dotori Guksu 심학산도토리국수

On weekends, names and party sizes go on a waiting list before the doors open, and some dishes sell out while people are still in line. The dotori jaengban guksu, acorn noodles on a platter, comes out almost as soon as you order, under plenty of cucumber and other raw vegetables; the noodles are a little firm, which older diners may find hard. The perilla sujebi is thick and nutty, and crisp acorn pancakes go with the cold acorn jelly soup.
