I think this club is the same as the executive lounge in Rc
Is Hilton going to be implementing this (i.e. higher tier club not available to Diamonds) at its other properties? I hope not. I came across an Eater DC article today with updated information about the hotel. Looks like it's unofficially open, and only hotel guests are allowed to eat at the new Voltaggio brothers restaurant located on the premises.

CITY CENTER—Top Chef alums Bryan and Michael Voltaggio opened the
anticipated Estuary at the new Conrad Hilton yesterday to a limited crowd of hotel guests only. The public can get a taste of its ceviches and puffer fish tails starting Friday, March 22, when the glitzy 360-room hotel officially opens. The super-modern hotel restaurant features lots of marble, wood tones, and pops of red lining the open kitchen.
Status: Certified open (for hotel guests only).
