Old City will get a Korean restaurant whose menu will emphasize comfort food, with a noodle specialty. Buk Chon - after the neighborhood in Seoul - is down for a fall opening at the former Zento at 132 Chestnut St., next to Adriana and across the street from Han Dynasty on the block with the Belgian block roadway. It's also a few doors from the new Glory Beer Bar & Kitchen at 126 Chestnut. Owners Chris and Alicia Chung previously cooked at Do Hwa, a popular Korean spot in Manhattan's West Village, according to Billy Creagh, a broker at National Realty in Old City, who handled the deal.
