The average major league baseball stadium is about 10 years old and costs approximately $500 million to build. The most expensive stadiums are those with the most luxury features, such as clubhouses, restaurants, and private suites. The New York Yankees' new stadium, Yankee Stadium, cost over $1.5 billion to build and is the most expensive baseball stadium ever built. The Boston Red Sox's Fenway Park is the second most expensive stadium at just over $700 million. Private suites can cost up to $2 million per season and include amenities such as a private entrance, concierge service, and access to VIP clubs. Clubhouses have state of the art training facilities and equipment, as well as luxurious locker rooms for players. Restaurants in stadiums are often upscale with gourmet food options and prices to match. For example, at Yankee Stadium you can find a steakhouse that serves an 8 oz filet mignon for $52 or a sushi rolls for $18 each. If you're looking for something a little cheaper, hot dogs and beer are always available at concession stands throughout the ballpark.
