You will be close to many great places. The restaurant at the Warwick is quite good. It is called The Landmark. You are also close to Capital Grille, which is always good (though since it is a chain, you might want to try something more unique). For less expensive fare, you might want to try Truluck's, Sambuca, or Javier's. All are excellent and a short cab ride from the hotel

The Library Bar is a quiet place for a coctail before dinner and later going to the fun and funky bars just steps' from the hotel. I also like Bellini's on Congress, two blocks from the hotel. Not upscale but good Italian and great Bellinis. Ask for Greta, she's a great server! Nope, I don't own the place, hehe!
