I live in San Diego and my wife and I eat out all the time.  We're in Ocean Beach, so we walk to The Joint, Blue Parrot, Village Kitchen, Pomas & Pepe's all the time.

I also work in the Mira Mesa area, and I eat lunch at a restaurant in that area 5 days a week.  Sima's, Tem's BBQ, Regent's Pizza, Uptown Delight approx twice a month each.

I have the MtGox app on my jailbroken iPhone to pay with.
