We've heard good things about these two upscale restaurants in Roma:

Agata e Romeo via C. Alberto, 45 tel. 39-064 465 842 closed: Sunday cost per person (without wine): 69$ all major credit cards

La Rampa (or Mignonelli ala Rampa), behind AMEX in Piazza Mignonelli at the foot of the Spanish Steps. One of the best antipasto tables in Italy. Closed at lunch on Monday.
