I treat myself to a slice of the most beautiful fig tart downstairs at Jolt N Bolt in San Francisco. It's in the same building as my office and you can actually smell some of the things they are making so it's hard to resist.
That's definitely a treat for me because I usually bring my own lunch and eat very healthy. I'm aware of the price of everything, but every once in a while I'll splurge. It is well worth the $2.50.
