The Champagne & Caviar Bar at RH Guesthouse New York is a bar inside RH Guesthouse New York that serves champagne and caviar. Its offerings pair caviar and champagne with a seafood tower and small bite dishes. Staff at the entrance direct guests down a wooden staircase, and the caviar tasting menu lets them try several dishes. Service can slow down, leaving stretches when water, champagne, and food are not refilled.
