Capital One Arena just knocked down the final wall between gambling and U.S. pro sports

For Leonsis, the future looks like a two-story, 764-person-capacity space plastered with 100 screens, 17 betting windows and a dozen betting kiosks. The entrance is on F Street, where the Greene Turtle used to be. Televisions cover the walls from eye level to ceiling. Betting kiosks line one wall, and on the other side of the first floor is a horseshoe bar with 24 beer taps. A board of odds and point spreads is displayed behind a counter where bets can be placed. A staircase leads to the second-floor lounge and restaurant, for which William Hill hired local chef Nick Stefanelli, known primarily for his Michelin-starred Masseria in Northeast Washington.
