Favorite Ice Cream?
I'll get the ball rolling with Bi-Rite on the northeast corner of Mission-Dolores Park. It is part of a locally-owned market and creamery, and the flavors are funky, in a good way. I particularly enjoy the Honey-Lavendar flavor, but I'm weird about ice cream. Nonetheless, they will give you free samples and have flavors for every taste (Salted Caramel, Brown Sugar, Roasted Banana, and the standard Chocolates and Vanillas of the world for those who are feeling less adventurous).
Be prepared to wait in line for about ten minutes before you are actually served. Don't let it serve as a deterrent, but rather a testimony to how good it is.
And they have the cutest photo on the homepage of their website: http://www.biritemarket.com/4.html
