Teeny-tiny Tight is always a good bet in Nonbei-yokochō, the narrow nightlife strip along the elevated JR tracks. Like the name suggests, it's a tight fit, but the lack of seats doesn’t keep regulars away: on a busy night, they line the stairs. Look for the big picture window. No cover charge; drinks from ¥800.
