Sorry to hear you had a disappointing experience at Maestro.
The RC Tysons Corner is certainly a second-tier Ritz, though incrementally better than Pentagon City.
Sounds like your meal at The Steakhouse was about what I'd expect. But that the Maestro problems began with having only one waiter assigned to your party. That's a huge blunder even if the waiter was especially talented, 14 people is simply too many for a single person to serve. And no doubt the service blunders colored the perception of everything else about the evening.
I'm a bit surprised to hear the chef's food there described as unflavorful, you may be the first person I've ever heard have that comment, but I don't know what you ate or what your particular tastes run like. Could have been of course that your dishes were coming off the station of a new member of the kitchen staff and for some (inexcusable) reason they weren't properly supervised. Hard for me to believe, but conceivable I suppose. Full disclosure: mrs. gleff used to cook there, but if anything that should bias me
against the place (since how could they possibly prepare a good meal without my wife there?

)
