Food and drinks at the stadium typically cost more than comparable items outside the venue. Exclusive concession contracts, private stadium operations and restrictions on outside dining have created a captive market that allows teams and suppliers to charge fans more, even though many stadiums were built with taxpayer dollars. Today, fans in many stadiums are a captive audience, with limited or no ability to bring in outside food, prompting lawmakers to propose legislation to cap concession prices at a fixed percentage above local street prices at publicly funded venues. But legal issues surrounding privately operated stadiums and the role of public subsidies have made it difficult to regulate concession prices.
