I am a huge fan of Groupon and other daily deal sites. They usually provide huge discounts and introduce you to new places you may not have tried if there wasn't a daily deal promotion.
The one draw back to daily deals is that I started signing up for dozens of daily deal enewsletters. It's been packing my inbox and become overwhelming. Then I discovered Deal Radar. It compiles all the deals in the area you define. I highly recommend this. http://www.dealradar.com
