The Total Fourth Avenue Immersion

This floating suds-soaked block party takes over Fourth Avenue as bars Mission Dolores, the Rock Shop, Cherry Tree and Pacific Standard serve complimentary Brooklyn Brewery beers, and local restaurants offer discounted snacks. Get one of the 500 free-but-necessary "immersion cards" which you must present to get the deals at Oaxaca (250 Fourth Ave at President St), where you'll also find $2 tacos, or Cherry Tree (65 Fourth Ave between Bergen St and St. Marks Pl), starting at noon.
