Okay, not really; but Google Maps seems to think the neighborhood has one down some sketch alley off of 25th.

(To Google's credit, there actually appears to be a “China Basin Heliport” somewhere in SF (airport code JCC), but it's most definitely not sandwiched between Capp and Cypress.)

(But seriously, how rad would it be to chopper in like Rambo for a round of bloodies at Phone Booth?)
