Contact Infusion Lounge

Infusion Lounge is ideally located at San Francisco’s world renowned Union Square within a five-block radius of more than 5,000 hotel rooms as well as the West Coast’s largest shopping center and the famous downtown theater district. For those coming from outside San Francisco, BART trains traveling into the city is a convenient option. Powell station is just one block from Infusion’s front door. If you plan on driving, you may find street parking or use one of the many nearby parking garages.

Infusion Lounge does not promote drinking and driving. In an effort to keep you off the road when you shouldn’t be, we offer discounted rates for our customers at the Hotel Fusion where Infusion Lounge is located.

Infusion Lounge is committed to your safety and security. In light of recent events in Orlando, we have increased security at the door to include metal detectors, bag checks, and close attention to dress code. We thank you for helping us create a safe and inclusive environment for everyone.

Dress Code: At Infusion Lounge we appreciate the ever changing world of fashion trends. We do however ask that all of our guests abide by our style code.

Several garages can be accessed within a few block radius of Infusion Lounge. We recommend using the 24hr self park Mason/O’Farrell garage which offers flexibility on what time you’d like to retrieve your car - a factor with some garages in the vicinity, as some close at or before 2am. Mason/O’Farrell garage is located just 1 block North / 1 block West of Infusion’s location (on the corner of Mason & O’Farrell). The adjacent hotel Nikko and hotel Parc55 both offer 24hr valet parking, but rates tend to run a bit higher. If you’re lucky, you may find street parking available nearby. Just keep in mind - some spots may be subject to tow-away (usually at 2am) for street cleaning, so be sure to read posted signs carefully.
