This restaurant is lively and hopping. It's usually pretty full so reservations are recommended along with valet parking 'cause street parking is limited. The pizza is good - thin crust. I found both locations - the original in L.A. as well as Newport Beach - to be consistent.
All in all we've been to Pizzeria Mozza in L.A. for dinner and Newport Beach for lunch and dinner and had a good experience all three times.
