Spent some time in the Centurion Lounge at DFW this week. It's across from d17, in one of those stand-alone buildings they have in there (above the duty free, by fuddruckers). Included services (meaning no money is exchanged) I see are locker luggage storage, high end liquor and custom cocktails, good beer selection, "quiet area," fast dedicated wifi, a nice buffet with "modernized" tex mex (plus the kitchen will make you regular stuff, sandwiches, chicken I f you ask), a spa with manicures/massages/skin treatments, PLENTY of electrical outlets, showers, and business center. The staff was extremely helpful and friendly. They do accept tips, so bring cash.
