The Cherry Blossom Festival is this weekend and next in Japantown in San Francisco. I tried the takoyaki (4 pcs of $2). Frankly, I couldn't tell if it was tako in there or not. Lines weren't bad at 11:30.
I'm volunteering there next weekend as well, so I'll have a chance to try some other stands (many run by community and church groups). So far, I saw sushi, spam musubi, soba, udon, unagi bento, teriburger and shave ice.
For dessert, I opted for a strawberry manju at Benkyodo (they don't have a booth, but the store is at Sutter & Buchanan).
