It is very nice. All the bells and whistles of Minute Maid Park, but a much more intimate atmosphere. 16 oz Draft beer is 4.50, plastic bottles 5.00. Cotton candy - 3 bucks, Cracker Jacks were either 2 or 3 bucks. Tickets were cheap, but the only available seats were outfield grass berm. It was a pisser because it rained it's ass off earlier that day, so the grass was going to be soaked and there were a shit load of empty seats all around. However, there are picnic type tables lining the left and right field concourse that you could sit at, and that is what we did.
I think my kids enjoyed the Hooks game more than an Astros game mainly because they were able to stand up and kind of run around a bit near the table we were sitting. There was a place for the kids to play in center field, but much of it was closed due to the weather. The ball throw and batting cage were both open for a buck a piece.
Leaving the game, my 4 year old said, "Dad, the Astros aren't my favorite team anymore...now it's the Hooks!!"
Oh, and another thing, Whataburger Field is the site of the 2007 Texas League All Star Game on June 26th.
