Zero

When dropping by Zero in Saiin, the natural place to begin is the signature Zero Set. Priced at ¥1,000, it lets you pick 3 drinks—with options including draft beer, Kakubin whisky highballs, Kodawari Sakaba lemon sours, and Akadama Punch (a wine soda made with Akadama Sweet Wine)—paired simply with a light snack. It serves just as well as an easy opener as it does for an unhurried evening of settling in across several rounds.

Those looking for a ready-made drink-and-snack pairing can opt for the Haikara Set, featuring fried chicken with a highball, or the nostalgic Red Wiener Set. Early in the evening, the pub also offers the Zero Morning Set, serving 2 drinks alongside a boiled egg and a small dish, letting you tailor your order to the hour and your mood. The kitchen backs this up with an unpretentious spread of small dishes, from small-plate sashimi and wieners with fried eggs to comforting hot tofu and closing bites.

Lined with posters, the room carries an understated retro feel, welcoming guests with an elongated counter and table seating deeper inside. Sitting down alone for a drink at the counter feels completely natural, and thanks to late-night opening hours, it is a reassuring destination whenever you want to unwind late around Saiin.
