Yup. The 4th that was available at SFO, Yankee Pier, is closed due to the construction. In some airports there's even other "experience" options, such as massages and sleep pods (generally only for an hour or so through). I will admit to twice having got a Priority Pass paid haircut at Singapore airport, where other options include about a dozen restaurants (although unfortunately most of them have moved to a "set menu" option only when using PP), or even the option to rent a bicycle (landside) for 2 hours - and yes, it thankfully it includes a shower afterwards...
