Luxury suites have become a major part of the modern ballpark experience, but few are as exclusive as the Cadillac Club at Citi Field.Hidden behind a members-only entrance near the players' tunnel, the speakeasy-inspired space offers complimentary food and drinks, a rotating chef-designed menu, and plush leather field-level seats just feet from right field.When the 100-seat club opened in 2023, access was initially available only through full-season club memberships, with first-row memberships costing $24,999 per seat, the Associated Press reported at the time.Last year, access expanded to some group sales, and more recently, "an extremely limited number of single game tickets" have been available for certain games, a spokesperson told Business Insider.Single-game seats are also being sold on third-party websites. As of July 22, third-row seats in the Cadillac Club for the Mets' July 25 game against the Los Angeles Dodgers were listed for $688 each.On a recent gameday between the Mets and Kansas City Royals, I was granted access to the Cadillac Club as a member of the press, eager to see whether the experience lived up to the hype — and prices.Here's what it's like inside one of baseball's most exclusive clubs.
