There used to be one in southwest Fort Worth in the Hulen area that did the whole "Texas fine dining" where they serve meat from animals that don't exist in Texas (like kangaroo and antelope) smothered in BBQ sauce or some other sauce. The beers ranged from good to mediocre (IMO). The food and beer was expensive and the service sucked ass -- no doubt why it was always incredibly empty. They closed around last summer or fall when lots of restaurants shut their doors. The brewmaster went to DC to work on some new project.
Humperdinks has a few good beers but a lot of their beers are so so. Very sports bar-like. Gordon Biersch has good seasonals and the schwartzbier is pretty good. The food is awesome but pricey.
Unfortunately DFW has lots of bars serving good beer with decent variety just not making it. I wish it were easier to get more US craft breweries in our bars though. We get the best of Texas breweries (Live Oak, 512, etc.) and no disrespect to them but there are lots of other US breweries I'd like to see make their way around to our bars.
There used to be a brewpub in the Stockyards when brewpubs first became legal in the 90s but it closed up pretty fast. It was stupid to open a brewpub in Miller/Coors central. It's all people drink there. Even the brewery that opened down the street from the Stockyards that made that kind of beer couldn't crack that market.
Although Two Rows doesn't make its own beer anymore -- the brewmaster opened Francona in McKinney -- it is proof that Dallas could support more brewpubs. Uptown, Addison, Victory Park, Arlington, Sundance Square, or 7th Street could all support a well planned brewpub. Heck, BJ's has exploded here just by taking on the suburban markets.
