Baltimore and DC info
In DC - Burgers - Palena Cafe, Central, or believe it or not Dino.
Wine Bar - Cork, 1720 14th S. NW, Vinoteca 1940 11th St. NW, or Proof 775 G St. NW (definitely one of the best wine lists too)
Steak house - subjective. Prime Rib is my favorite for a mix of great steak and that old time "Mad Men" feel. There is one in both Baltimore and in DC. Ray's the Steaks is great for a no frills, great steak, but it is in Arlington.,
Hotel dining - Plume in the Jefferson Hotel (very expensive), CityZen in the Mandarin Oriental, or the Blue Duck Tavern in the Park Hyatt.
