Located on the eastern edge of LoDo, Cafe Berlin hadn't caught my eye until one sunny day a few weeks ago when the half-dozen patio tables were filled with patrons whose laughter carried down the street. Unfortunately, it was too windy to sit on the patio the day I returned, so I pulled up a seat at the bar, just inside the front door. Seconds after I sat down, a framed sign grabbed my attention: "If you are grouchy, irritable, or just plain mean, there will be a $10 charge for putting up with you." That's when I knew I was going to like this German spot just fine. And don't let the neat white linens on the dining room tables fool you---at least not during happy hour, when you'll easily feel at home in jeans and a T-shirt. After figuring out whether I wanted a third of a liter, a half liter, or a full liter of beer (the half liter is closest to a pint), I ordered a Paulaner Salvator Doppelbock---a perfect companion for the bratwurst and sauerkraut appetizer---and enjoyed the quiet setting and array of ornamental beer steins. Happy hour runs 3 to 6 p.m., Tuesday through Sunday, and gets you one dollar off any of Cafe Berlin's draft beers, well drinks, or wine by the glass. 323 14th St., 303-377-5896
