After a hundred years in Little Italy, Grotto Azzurra is holding down its history as host to Caruso and Sinatra; that same hospitality extends to the travelers and locals who pack the restaurant. A prix-fixe lunch menu is still under $10, and homemade pasta specialties are fine starters to entrées like veal Milanese and osso buco. The brick-lined wine cellar room is particularly lovely and great for large private parties.
