Tiny but bustling Koreatown is packed with Korean BBQ restaurants, where a young, affluent crowd dines late into the night after stops at nearby karaoke lounges. Dessert cafes serve colorful rice cakes, and shops sell Asian groceries and beauty products. Numerous spas offer massages or sauna time. At leafy Greeley Square, visitors can sample creative bites from local chefs at a seasonal food-cart pop-up.
