Hitsujiya Yongsan is an izakaya near Yongsan Station serving Japanese-style lamb and all-you-can-drink alcohol. The all-you-can-eat course includes lamb ribs, sukiyaki nabe, and lamb cheese hamburg, and staff grill the first serving of meat. The interior has a retro look reminiscent of an izakaya in Osaka, Japan, with drinks such as melon soda and highballs. Seats are cramped, and orders and refills are slow, creating waiting time during the meal.
