If you happen to get invited to the San Francisco Ballet because a friend has an extra ticket and you go and you love the performance, with its sublime production of the germanic nanna's lied, then you should also grab some dessert downstairs, rushed, in an intermission, chocolate served between the dances.

Now twice someone has mentioned Taco Portal, a psychedelic trance affair at San Francisco's Border Cantina. This is irresistible. I will be there next thursday or next.
