Casino operators have been expanding sports betting facilities and products, as well as renovating and upgrading equipment and facilities. Although sports betting has a relatively low margin, the high-end sportsbooks can generate significant amounts of revenue in other areas, such as food and drink. As a result, sportsbooks have been expanding and upgrading foot and drink offerings. High-end sportsbooks include features such as single-seat stadium-style seating, large high-definition screens, a dedicated broadcast booth, and the ability to watch up to 15 sporting events at once. The sports network ESPN is broadcasting sports betting shows from a dedicated studio at The Linq. Some sportsbooks are now offering self-service betting kiosks.
