For some reason I keep thinking Angels in America is at the Walter Kerr, so I was going to suggest P.S. Kitchen, which is right across the street from the Kerr. HOWEVER, I would still suggest it to anyone who is looking for a great vegan/vegetarian restaurant in the Theater District. I am neither a vegan nor a vegetarian, but went to a work event there and the food is delicious.
When I see the phrase "the ____ estate", I imagine a vast mansion in the country full of monocled men and high-collared women receiving letters about productions across the country and doing spit-takes at whatever they contain.
