About Lower Nob

Hill

Lower Nob Hill, located between Union Square and Nob Hill, is a compact and historic San Francisco neighborhood with steep streets and early-20th-century apartment hotels. The neighborhood’s character concentrates around the Geary Blvd and Leavenworth St corner, where late-night eateries, corner markets, and marquee-lit venues set a brisk, urban cadence. Architectural details lean toward brick and stucco mid-rises, bay windows, and ornate lobby entrances that hint at the area’s hotel-era roots. The Great American Music Hall anchors the cultural calendar with a storied stage and gilded interior. Café Mason and the Tonga Room & Hurricane Bar add a classic, old-San-Francisco layer to the daily circuit.
