I came across this link from Draft Mag. 4 beer bars from Texas made the list. Draught House, Petrol Station, The Hay Merchant, and Strangeways. Hooray beer bars. http://draftmag.com/new/feature/america-100-best-beer-bars-2013/
I haven't been to Hay Merchant yet but the other 3 are my favorite bars in their respective cities. I really think Easy Tiger is catching up to Draught House, I spend equal time in both those places when I visit the ATX.
Hay Merchant is pretty awesome.. but I like the outdoor roominess of Petrol Station a bit more.. both get great beer.
