Zocalo is one of my favorite places to hit for happy hour. With an awesome patio, cold drinks and great Mexican food, what more could you ask for? Free food you say? Well, they have that covered too.

Sign up for Zocalo's e-mail newsletter and get a certificate for a free appetizer.

When you get the coupon, just print it out and bring it to the restaurant. Best of all, there's no expiration date, so you can use it at your leisure.

Zocalo is located at the corner of Capitol Ave. and 18th St.
