I'm going to check out the food and entertainment at the Aloha Festival this weekend at the Presidio in San Francisco. 10AM - 5PM both days, admission is free, though parking is $5. This is the annual Pacific Islander culture festival.
I'm specifically looking for malasadas (the lines were huge last year) and unusual jams and jellies (hopefully I can find poha). I'll report back if I find anything good there.
