As evidenced by the photo the team store is a big hit.  Very few fans come to the game not wearing "Cardinal red" or a branded piece of clothing.

The typical baseball fare can be found throughout the stadium but there isn't as much variety as you might want.  They stands do have some clever names like El Birdos Nachos (nickname given to a team in the 60's).  The redeeming factor in food, however, is Hardees.  Their national headquarters is in St. Louis and they grill fresh Thickburgers and let the smell waft out over the ballpark all game long!
