You must go here. It’s crowded but the hot fudge, my friends, is worth the wait. Not many touristy places will get my endorsement, especially in San Francisco, but you must trust me here. If any part of your tooth is sweet bring them here. 

Interestingly enough you can get a hot fudge Sunday just like this at AT&T park while watching the Giants play. Who needs beer and hot dogs when they can have this?
