While best known for their burgundy restaurant guides, Zagat is now making a foray into San Antonio nightlife. It involves a public survey of more than 250 of the best bars, nightclubs, music venues, pubs, lounges and more. Over the course of the next few weeks, the company'll gather thousands of ratings and reviews from locals of the best — and worst — of SA's after-dark options, then turn the data over to a local editor to compile the results. During the editing process, the Zagat staff pulls the best quotes and quips of each venue and turns those into their signature editorial reviews. In this way, Zagat reviews give readers the opinions of thousands, without the hassle of reading thousands of reviews. To participate in the survey, you'll see Zagat voting booths at some of your favorite summertime activities, like First Thursdays at Pearl, San Antonio Missions games, and Jazz SA'live. You can also vote at home from your computer, and they're offering $50 Biga on the Banks gift cards to two lucky SavorSA readers who vote in the survey, but the chance to enter ends this weekend. All voters are also eligible for free Zagat rewards, like a free Zagat guide once you've submitted 15 votes or free Zagat culinary merchandise once you've completed 40 votes. We can't wait to hear everyone's pick for San Antonio's best nightlife spots! Click on the burgundy Zagat ad above to enter the Biga contest and start voting!
