The Market Square area of downtown isn't bad. You have Warren's and La Carafe ON the square, but within walking distance you have O.K.R.A and Hearsay. Walk down a block to Travis and Franklin and there is Houston Watch Company (my new fav small bar) and Public Services Wine & Whisky (in the Cotton Exchange Building). Main St. between Preston and Congress is lined with bars.While I've not been yet, I understand the show and dinner at Prohibition is well worth it. http://www.prohibitionhouston.com/
