On the night before Valentine's Day, we helped a few San Franciscans celebrate their love affair with the city, while getting a little tipsy on a streetcar. For the fourth installment of our Best F'ing Party series, our cocktail events on the F Line, we took a starry-eyed group on a moonlit tour.

Guests hopped on board at the ever-enchanting 17th and Castro Muni stop, where they were greeted with a Mediterranean spread and seasonal cocktails.

The 29th Street Swingtet kept everyone in the mood with their Django Reinhardt repertoire and a few Outkast covers thrown in for good measure.

We rolled down Market Street and The Embarcadero, talked to friends, and made some new ones.

Here's hoping that the swoon-worthy sites we saw inspired this guy to cap his night with a sweet goodnight to a Valentine. Or a booty call would be just fine, too.
