BluWater Bistro at Carillon Point is no more. The doors are chained, the Kirkland location has been removed from the company's website and a sign in the window reads, "BluWater Bistro has CLOSED for Business. Please fee free to visit one of Carillon Point's other fine dining establishments just off the Plaza level: Beach Café, Poppinjay's Café and bin on the lake."
According to this article in the Seattle PI Inside Belltown Blog, the restaurant's owners have also closed the Belltown Bistro. The group also owns BluWater restaurants on Eastlake, Greenlake and Leschi.
