You might very well already be too late to get anything on the romantic side.
I'd try for Bistro de Paris, Citrico, the California Grill, Jiko, Artists Point, the Yachtsman Steakhouse, Blue Zoo, and Shula's.
FYI for anyone headed to DTD that night, there is a sold out show at the HoB, expect crowds to begin lining up around 4:00pm to get in. The band is called Disturbed to give you an idea of the audience... They actually are a good band if you're into that type of music
