If you are using a GPS or something make sure it gives you the downtown location and not the west O location or you will be making a 20 minute drive to steve dave's hood
Downtown location is:
514 South 11th Street
Omaha, NE 68102
You could walk there from the stadium but it's about a mile. You could probably park somewhere in the Old Market and walk to the game and then walk back to the restraunt (is what I'd do).
