Coolest feature: The Dr Pepper Bottling Plant. It's not an actual bottling plant, but if you love this signature Southwestern soda, they serve a Dr Pepper BBQ brisket sandwich and a Dr Pepper Chicken Tender Smasher, neither of which you will find elsewhere.
If you dumped the Mavericks home on the tarmac at DFW, nobody would bat an eyelash -- it could easily pass as an old airplane hangar. Mark Cuban has created an experience here that's both fan-friendly and pure business genius: tickets start at about $10, but the in-arena offerings are so tempting you'll be hard-pressed to walk out without dropping a lot more cash. There's a Texas beer bar (that pours local favorites like ZiegenBock, Saint Arnold's, and Firemans #4), a Woodbridge wine bar, and bars that serve barbecue, steak, and even gourmet cookies. There's also an attached nightclub and ultra lounge, PIRA, which stays open until 2am after games and is open to the public on non-game nights.
