We plan to take the metro in from Fairfax to meet friends who will be staying at the Marriott Residence Inn on North Oak Street in Roslyn next month and are in need of suggestions on restaurants within walking distance. We'd prefer a place where we can hear each other (low decibel??). It will be mid-week, probably around 6:30 PM. Something similar to Les Halles or Clydes or Arties (cuisine and price range)? Thanks.
