Norcini - Santa Monica Place
If you want the most comprehensive selection of salumeria and cheese go to Norcino located in the Market at Santa Monica Place. This is the creation of Piero Selvaggio and nobody sources ingredients better than Piero. Primi has closed but Norcini is going strong and has gotten me through many Sundays of football watching. See pics below.
The Cheese Shop in Beverly Hills is the gold standard.
It has no peer. Norbert probably knows more about cheese than anyone I have ever met. The cheese counter at Surfas, although small, has a lovely selection of cheese and charcuterie. Both The Cheese Shop in Beverly Hills and Surfas in Culver City are very generous with samples.
