On the 32nd floor of the Sheraton Grand in Seattle is the Club Lounge. Accessible to qualifying guests (Bonvoy Platinum, Titanium, Ambassador, etc.), the food is constantly refreshed and suited to the time of day. In the morning, for example, they served sausages and eggs in addition to the fruit shown here. The staff is cheerful, given how chaotic the lounge can be.
I'm not complaining, but the lounge is crowded during breakfast and dinner hours. That said, the lounge is quite large and would comfortably accommodate, say, forty gests. Later at night, it's often empty and peaceful.
