It's hard to resist bite-size (or two-bite size) cupcakes.
Today on Groupon, you can buy coupons for two dozen mini cupcakes from Mission Minis, for $12. It's a $30 value. You can buy two coupons (but only use one at a time). The coupons are good for a year.
Mission Minis has two shops - one on 22nd Street (and Mission) and one on Union Street in North Beach.
