NFL American football franchise the Arizona Cardinals opened up the University of Phoenix Stadium to the media at the weekend to show off a series of upgrades as part of a $28m (£22m/€24.6m) renovation initiative.

Work has been ongoing for the past two years and all improvements have now been completed ahead of the 2018 season, which kicks off next month.

New upgrades include the creation of ‘The Tail Feather’, a lounge and full-service bar located on the northeast side of the stadium.

Other club level upgrades include new bars and food service in all four corners of the venue, as well as new flooring and lighting, additional televisions, new sound system and new furniture.

Elsewhere, a specialty lounge area called the ‘Bird’s Nest’ has been built to offer a bar and buffet to visitors, while all restrooms across the club level have been completely renovated.

Cardinals president Michael Bidwill, who led the media tour, said: “We knew from focus groups and some of the other research that these were going to be very popular. But (it’s) until you actually hear it from the fans on game days.”

Phase one of the renovation, which was completed last year, included 10 extra beer taps in the club level, as well as the addition of large videoboards added to the primary 50-yard lounges.

Earlier improvements also included the creation of ‘Flight Lounge’ bar and the ‘Bubble Lounge’ high-end, full-service bar.

Bidwill added: “The stadium has never looked better.”
