Kyopao Gyōza Shinjuku Higashiguchi Ekimae is a Taiwanese-style suigyoza izakaya connected directly to the underground passage at Shinjuku's east exit. The signature kyopao comes with a choice of soup among baektang, malatang, and huoguo. On weekends it opens from midday with no break and a self-drink bar lets customers fill their own glasses. Being underground, it is hard to find from outside.
