"Great stop in downtown Harrisburg for beer lovers. They had 15 beers on tap when we went. They also had wine and cider, which made my wife happy. Unlike most breweries, Zeroday also has a few hot food options, including a giant soft pretzel.
The tasting room is painted orange and is nicely appointed with bright artwork. The only downside is that it must get packed as the place is simply not that large inside- a bar and maybe 10 four person tables. No huge social tables for larger groups.
Their beers are excellent with lots of styles to choose from.
Lots of parking too (though maybe not when movies are playing next door).
Will definitely stop by next time I'm downtown."
