Desperately seeking San Francisco restaurants

Barring a last minute cancellation, it looks like we will NOT be going to the French Laundry. Thanks to everybody for the support and help!

Life goes on and so we are going back to our first love: hole in the wall restaurants.

If anybody knows of good ethnic hole in the wall restaurants in the Bay Area (preferably within the San Francisco City limits but we will have a car and will drive a reasonable distance out of the city for good food), please let us know.

In particular, we are hungering for food that we can't get easily in Vancouver, such as Cuban and *real* Mexican food.
