Dirty Habit holds the fifth floor of Hotel Zelos, a SoMa terrace bar a block from Union Square where the heat lamps run year-round and the cocktail list does the heavy lifting.

Dirty Habit sits at 12 4th Street, on the fifth floor of Hotel Zelos in SoMa. The Rooftop Guide lists it among the city's open-air terrace bars, and the hotel's official site frames it as a craft cocktail room with an indoor-outdoor terrace. The setting is the hook: a covered, heated deck that turns San Francisco's chilly evenings into a usable patio, set above the street noise yet steps from Union Square.
The pull is the terrace and the program together. This is a place to start a downtown night with a proper drink, not a view-only rooftop that leans on the skyline alone.
The room
The space splits between a sleek indoor bar and the open-air terrace, the part most reviewers come for. Heat lamps and greenery make the deck the seat to ask for, and the room runs polished and design-led, in step with a hotel bar near the shopping core. It fills with an after-work and pre-dinner crowd on weekday evenings and turns more social on weekends. Glass and greenery wrap the terrace, and a retractable cover keeps it usable when the fog rolls in, which is the detail reviewers credit for the year-round crowd.
What to order
Order from the craft cocktail list, the menu the bar is built around, and pair it with the New American small plates meant for sharing on the terrace. Expect downtown hotel-bar pricing, with cocktails in the upper-teens range. The move is a terrace seat and a round at sunset before the dinner crowd arrives.
The crowd and best time to go
The crowd is hotel guests, downtown professionals after work, and groups starting a night near Union Square. The bar runs daily from 4pm to 11pm, so the early evening is the window, and a terrace seat is easiest before 7pm on a weeknight. The room turns more social as the dinner crowd arrives, so the early window stays the best bet for a quiet drink.
What regulars say
Across Yelp and Tripadvisor the steady praise is the terrace, the heat lamps, and the cocktails, with the outdoor seating called out most. The common note is the hotel-bar pricing and a room that gets busy at peak, so an early arrival reads as the smarter play. Visitors staying at the hotel and downtown workers both cite the convenience of a real cocktail program a short elevator ride from the street, and the small plates draw praise as a shareable anchor for a round on the deck.
Who it is for
This is for the downtown date, the after-work group, and anyone touring San Francisco cocktail bars who wants an open-air seat with a serious drink. Skip it if you want a dive or a budget round. For the wider city, see the full San Francisco bar guide.
The verdict
Dirty Habit earns its spot by pairing a usable, heated terrace with a cocktail list that holds up, a harder combination to find downtown than it should be. Take a deck seat near sunset, order a craft cocktail, and start the night above the street.
