Happy Hours: The iPhone App
It's chock full of the good stuff: you can view menus, comments and, of course, happy-hour specials all around town. Here's the best part: When you shake the phone, it makes an ice-in-glass sound and picks up your favorite bar or restaurant.
Oh, and it's available in 35 cities around the country, including, of course, Dallas. Click through and see Happy Hour details like menus, location and comments.
