For on-the-go besotted frugality, this just-launched iPhone app first geo-locates you, then lists the 10 nearest happy hours in order of starting time (e.g., $1 Slane well drinks in 22 minutes, $4 Hop Devil select pints until 7pm, etc), plus GMaps them for easy wayfinding. The app also lets you search happy hours by hood & day, and even creates a customizable clock face that displays the time frames of your faves (what time is it? Time to get swill).
