I decided to wait out the traffic in San Mateo last night, and using my Chowhound guide, sought out Ma Pinkie's BBQ and Soul Food. It turned out that Thursday was their next-to-last night of regular business. They're open tonight, and Saturday she said they're having "a big party at the rec center with a band." She said they might try to find a new location (certainly the old one was no prize -- I had a heck of a time finding it).
Sad really. Not great BBQ, but clearly a place that has "soul."
