Manhattan c'hounder in town for mother's day...i really want to treat my mom to a great brunch on sunday and would love local suggestions. Any area of DC is okay, but if you need specifics i would say downtown, dupont circle, georgetown, or u street corridor. My mom is young and not at all stuffy so a fun and hip location would be a plus. So far i've heard about: Brasserie Beck, Farenheit (at the ritz), Tabard Inn, and Cashion's Eat Place. What do you guys think? Thanks!
