OK, we've never done this before but the Chile Man sent us an email so we're going. Lots of beer vendors, and some food vendors.
Admission free, $10 for a commemorative mug and two tastings, after that tastings are $2 each. In Shirlington Village, which is sort of hard to get to unless you know where you're going. 2700 S. Quincy St., Arlington VA (703) 578-3888
While you're in the neighborhood, take a detour to M. Slavin seafood, 2710 South Glebe Road, Arlington, VA 22206 (703) 486-0400.
Mapquest it first, otherwise don't yell at me! ;^)
