In which we walk into a bar, unannounced, and ask the bartender to make us his or her favorite drink.Establishment: Lounjin, 4527 University Way N.E. 888-2827Barkeep/Barista: Jin An (He’s the “jin” in “lounjin)Ok, Jin in Lounjin, what do we have here? This is called a Fruit Tree. It’s a Okuno sake accompanied by five different flavored sakes: raspberry, Fiji apple, lychee, plumb and Asian Pear served over ice.Jin says that the Okuno sake is the basic part. It’s 24 percent alcohol. The others are all 18 percent. This Fruit Tree is listed on the menu under the “ass kicker” section. “Most people under estimate the strength of it,” he says, noting that alcohol are usually categorized: beer, wine, then hard alcohol. “Sake occupies this middle spot. It tends to hit people pretty hard who aren’t used to it.”Jin is by far the most affable bartender/barista I’ve met on First Calls. He’s very happy to hang out and explain the ins and outs of sake to a sake newbie. Lounjin, located on the Ave., has been open for about a year, Jin says. And the place is aptly named. Lounjin, isn’t so much a bar as a cafe. There’s a couple of high, four-person tables and three couches surrounding a giant-screen TV showing the NBA playoffs. Jin says that his establishment tries to cater to all patrons. Sometimes groups are split on their preferences of the moment. Some people want coffee, some people want alcohol, but they all want to chill. For those groups, there’s Lounjin, he says. The place serves beer wine, coffee and, of course, sake.This isn’t bad Jin, it’s a bit like a Long Island Ice Tea, only not as sweet. Yeah, but it’ll hit you hard. When Tommy’s was open across the street, people would come in here after a few beers and be fine. Then, they’d have a few sakes and be on their faces. It hits different people different ways. So, how did it hit me? I found myself driving home with the windows down blasting Metallica — old Metallica. I’m not sure whether that’s scary or really really cool.
