This club is as sleek as its namesake, a polished precious stone in a world of rough rocks. The decor is ultra-retro and swanky, attracting a hip crowd in cool clothes and with even cooler attitudes. The bar is beautiful and made of onyx, which is really something to see. Live bands play here often and there is a healthy-sized dance floor for those who are interested in more than just posing with a martini.

This bar is housed in the oldest building in the Gaslamp Quarter. Come and mingle with beautiful people and groove to either live music or a DJ with tunes from the 1970s through the 1990s. Hardwood floors, soaring ceilings and a 40-foot long mahogany bar give a touch of elegance and class. There are three levels, all offering a large number of beers and delicious cocktails.

For a dose of live music while having your local American grub, head to Whiskey Girl. The club resembles Hard Rock Cafe with its set of nightly bands performing with enough vigor to make you sit back, tap your feet and clap for every song asking for more. The odd nights also have DJs spinning some fine tunes from their collection. There are ample televisions to keep you entertained with ongoing sports matches if the music isn't of your liking. The American cuisine dominated menu features an array of burgers, sandwiches, salads, classic pub appetizers, pizza and more. Their Sunday brunch is also noteworthy!

This lounge bar and nightclub keeps it trendy and chic. If you want a nice and well-lit evening locale to have some cocktails with friends, Side Bar is the place for you. At night, dance to beats by local DJs in a luxurious atmosphere. Ambient lighting and art make Side Bar a stylish addition to San Diego's nightlife landscape.

If you like to dance and party all night long, then Spin is the place for you. The club houses three levels, five rooms, four bars, pool tables and a rooftop smoking patio that overlooks downtown. One of the rooms features the latest hip-hop tunes. The club's big screen video and monitor walls and laser lighting give the effect of being at a rave. The warehouse-esque building adds to the modern atmosphere. Not suitable for quiet conversation, this club is for the lively party crowd.
