Looking for a free glass of wine? Â Our friend Yael tipped us off to this promotion that Cavatappo Wine Bar is currently hosting. Â Like the wine bar on Facebook, and you’ll be directed to a site where you can register with your email and birthday. Â You’ll then receive an email for a complimentary glass of wine. Â Print out the email, bring it in to the wine bar, and you’ll be all set.
