Depending on when you travel, high season or off will make a huge difference in how many buffets you encounter.
We were there in December and the Trattoria at Portofino had a wonderful breakfast as well as dinner buffet. We just returned last month and went to the Trattoria and was so disapointed to find that if was menu only. I happened to ask and was told that it was a waste of food and money to offer a buffet when crowds are low.
I would give both hotels a call closer to your travel dates and ask if the buffets are back.
Latin Quarter also had a lunch buffet in December and that as well was not being offered last month.
They were serving a buffet at Hard Rock's Sunset Grill. A full buffet and also a continental breakfast buffet.
If I can think of any other buffets I will post them.
