A.J. Rathbun, our good buddy and prolific author, whom we’ve written about not one time, but twice for The Seattle Times Pacific Northwest magazine, has done it again.

But this time instead of another book (among which he has written “Ginger Bliss and the Violet Fizz,” the award-winning “Good Spirits,” and a host of others), this time A.J. has come up with his own app: Drink Seattle: A Spirited Journey Through Seattle Bars and Cocktails with A.J. Rathbun.

The Drink Seattle app costs just $1.99 in the iPhone App Store, with an Android version coming soon.

In the app, A.J. Rathbun, awarding-winning author of a host of cocktail and home-entertaining books, recommends over 50 of the best bars, cocktails, distilleries, and cocktail supply shops in and around Seattle.

And whether you’re visiting Seattle or already live here, if you like a good drink, you need this app. With the ever-jovial and witty A.J. as your guide, you won’t miss a lounge, bar, distillery, or dive that’s worth sitting down and sipping within.

This bubbly whirl gives you a great drink in nearly every neighborhood, specific cocktail picks for each place and a host of insights on individual bar personalities.

Each recommended establishment features a detailed review, notes on what to order, and great photos and tips for having the best experience you can.

As you’d expect, the app has a lot of bells and whistles–GPS, one-touch dialing, and turn-by-turn directions – and vital info like business hours, websites, etc. And, awesomely, the app is updated frequently so you stay abreast of all the latest changes in the Seattle cocktail scene.

A.J. knows from whence he writes, since he pens the monthly Bar Hop column for Seattle Magazine and a weekly blog for them on spirits, cocktails, and bars, as well as authoring his own tipsy blog Spiked Punch. He’s a frequent guest on the Everyday Food program (Martha Stewart Living/Sirius satellite radio), and a contributor to culinary and entertainment magazines such as Every Day with Rachael Ray, The Food Network Magazine, Real Simple, Wine Enthusiast, and many others.
