I almost never buy food at the stadium, the prices are just wayyyy too outrageous. I get to the park area early and hit some of the local establishments instead. I usually get to Baltimore at least once a year for a O’s game and usually stop at Fraidley’s for a crabcake. Then I’ll get a hotdog or sausage sandwich to take into the park with me.
Up until the 2002 season they would let you in and out of the park at will. There was always a number of vendors right out front that were a whole lot cheaper then inside.
