Swig live music bar took over a beloved member of a group of San Francisco live music bars, called the Blue Lamp. The new owners gave it a modern update, but have continued the old Lamp tradition of the Sunday evening electric blues jam from 9pm to 2am. Weekdays, there’s live jazz, blues, and other bands. On the weekend, starting Thursday, DJs man the decks and things get busy. It can be a real scene, packed with thirty-ish beautiful people and those who watch them. The décor has retained its soul, including a huge window up front that slides open, inviting passersby to join the party. Later, the fireplace heats up. Later still, the crowd makes its way upstairs into hidden areas for chatting and nuzzling.
