In the Dallas Marketplace area Peticolas is the best brewery of the lot. I'm not too well versed with the breweries in that area that opened in the past year (e.g. Pegasus, Steam Theory, Manhattan) but I haven't been a great fan of what I've tried from them. A lot of people like Community, which is also nearby, but not a big fan personally.
In that area is Meddlesome Moth which is definitely on the short list for best beer bars in Dallas.
If you aren't familiar with Dallas or this part of Dallas it's worth knowing this is not a particularly walkable area so anywhere you go you'll need a car or the rideshare app of your choice.
