OOSTEN Realwirtschaft am Main ★ 4.1
€€€ostendMon-Fri 17:00-23:00; Sat 12:00-23:00; Sun and holidays 10:00-22:00
OOSTEN's multi-level terrace around the old harbour crane gives Frankfurt its open-air riverside nightcap, skyline lit across the Main until closing.
Tip: The upper deck at dusk is the shot everyone posts; drinks-only visits are easiest on weeknights.
The Tiny Cup ★ 4.4
€€altstadtWed-Sat 18:00-00:00; occasional Sunday events
The Tiny Cup hides its cocktail counter inside Frankfurt's narrowest house at Mainkai 4, the closest the city comes to a speakeasy in spirit.
Tip: Blink and you miss the door under Seven Swans; the drinks list changes with the restaurant's farm harvest.
Harvey's ★ 4.1
€€nordendMon-Sat 09:00-01:00; Sun 09:00-00:00
Harvey's is a fixture of queer Frankfurt, a Nordend corner cafe-bar named in the Harvey Milk tradition, open from morning to well past midnight.
Tip: It works as brunch spot, evening bar and community landmark in one; the terrace is the scene in summer.
Café Größenwahn ★ 4.1
€€nordendDaily from 16:00; kitchen Mon-Sat 17:00-22:00, Sun 17:00-21:00
Café Größenwahn has mixed queer culture, politics and dinner on its Nordend corner since 1978, Frankfurt's longest-running scene institution.
Tip: Come for dinner and stay for the room; the walls carry nearly five decades of Frankfurt counterculture.
Klapper 33 ★ 4.0
€sachsenhausenSun-Thu 19:00-02:00; Fri-Sat 19:00-05:00
Klapper 33 is Frankfurt's dive of record, a smoky Klappergasse Kneipe that keeps pouring until 05:00 when the weekend demands it of the room.
Tip: Cash only in spirit if not in fact; this is where Sachsenhausen's bar staff drink after their own shifts end.
O'Reilly's ★ 3.7
€€bahnhofsviertelMon-Thu 16:30-00:00; Fri 12:00-02:00; Sat 12:00-03:00; Sun 12:00-00:00
O'Reilly's works the graveyard shift opposite Frankfurt Hauptbahnhof, pints and stray travellers until 03:00 on Saturday nights and first trains.
Tip: Between a missed connection and the first morning train, this room has sheltered generations of the stranded.
