Shorter lines than Bi-Rite and the ice cream flavors are so different. Try the Secret Breakfast (Bourbon and Corn Flakes) and the Blue Bottle Vietnamese Coffee - those are a MUST!
Lots of great roasters (ritual, blue bottle, etc) but Four Barrel beans are incredible. The crowds is uber mission trendy. get a good grinder and make a nice cupper.
fruit - whatever is in season from Frog Hollow, coffee - Blue Bottle, bread - Acme, breakfast during Sat market - Primavera & explore the dozens of great shops & farmers!
Aside from great coffee the redesign of the store is amazing. By far one of the coolest looking shops in SF, along with Four Barrel and Blue Bottle
Fans of single-origin pour over coffee, stop by, grab a cup, then sip it at the lovely Hayes Valley park.
