From that list I would definitely look into Manny's or Herrera's. For BBQ I would recommend you try Pecan Lodge, which is just a couple miles West of the Convention Center. Go for a late lunch or early dinner, otherwise you will be waiting in a line that wraps around the corner. A few miles South of Dallas is a BBQ place called Lockhart Smokehouse that is pretty great as well.

Try some of the local beers as well. Lakewood's The Temptress is a fantastic milk stout. Anything from Peticolas, Community or Franconia will be thoroughly enjoyable as well. Revolver Blood and Honey is real popular with the ladies, but at 7% it isn't a "girly beer."

When you want something easy to drink you can move on to Shiner and Rahr.

Enjoy the trip here (in spite of Dallas) and hopefully I will get to meet some of you guys while you are here.
