About STIIIZY Union Square

Our fourth STIIIZY retail dispensary in the heart of San Francisco is located at 180 O’Farrell St, San Francisco, CA 94102 in Union Square. Conveniently located in downtown San Francisco near the vibrant central shopping, hotel and theater district, STIIIZY Cannabis Dispensary Union Square is the first Latina-owned cannabis store to open through the city’s Cannabis Social Equity Program.

Since this Union Square dispensary is in such a culturally diverse area, it proudly serves the communities of Mid Market, Tenderloin, Belden Place, The East Cut, South Park, South Beach, Chinatown, North Beach, Cathedral Hill, Opera Plaza, Polk Gulch, Union Street, Russian Hill, Northern Waterfront, Fort Mason, Marina District, Pacific Heights, Cow Hollow, Japantown, Fillmore District, Lower Pacific Heights, Fisherman’s Wharf, Embarcadero, and beyond.

It’s also close to the Cartoon Art Museum, the Exploratorium, Central Embarcadero Piers Historic District, the Asian Art Museum, the Contemporary Jewish Museum, the Museum of the African Diaspora, and the San Francisco Museum of Modern Art, as well as Lafayette Park, the Civic Center Plaza, Alta Plaza Park, and Yerba Buena Gardens.

This dispensary has a stunning (and calming) hand-painted mural done by artist Mars1.

One of my favorite places to shop whenever I’m downtown I make it a point to stop in and say “hi” shout out to my man Junior for recommending some nice “nugs”. 💯

The staff here are extremely knowledgeable about the products they sell. They encourage you to take your time and ask questions. The amount of products to choose from is awesomely ridiculous!

Man Mike helped me out so much! Got me in and out and at my price range. Great customer service and he even helped me out with a few bucks towards my purchase. This is my first time posting a review so this should say a lot about my experience.
