+1 to Sunset Grille.
Also its a good time of year for oysters and you will find them all over the city. Union Oyster House is famous and good, just try to go at off peak times. My M.O. in the city is to go to pricier restaurants for a late lunch. Same thing for less money and better service/quieter. Hit bars/clubs with live music at night.
If you like Jazz go to Wally's on Mass Ave, especially on Tuesday nights.
