Not particularly Italian— but the crêpes and tomato bisque soup make a nice change of pace from the usual hotel breakfast in Honolulu. Refillable coffee is available à la carte. You need not choose the whole juice-coffee-yoghurt buffet.
It is easier and less noisy to get an inside table. Service is very agreeable and very polite. The newer Beach Walk branch at the other end of Waikiki may be more authentic for full-scale wining/ dining.
Beware the Marriott's validated valet parking charge of $12. Walk instead!
