i'm a regular, and since i work at home, i end up there at off hours and see the same people as well. Steffan says things are usually busier in the after work hours, and it looks like stuff is selling (a couple of my favorites have sold out here and there). he's also hiring, which is a good sign.
in terms of wines, Rieslings are a good bet. i've found that German Kabinett Rieslings are at the low alcohol end, as a rule.
