I'm going to brunch with my sister and sister-in-law. My sister is from Manhattan and likes swanky places with high prices and small portions. My sister-in-law is from LI and enjoys low-key places with low prices and large portions. I'm happy at either. I am looking for a Sunday Brunch preferably buffet. My favorite is Garden City Hotel but that's too over the top for my SIL. Please help me find a happy-medium for these two!
