Neil,
So glad that you and your family are coming down to the Southern California area!!
The Magic Kingdom? Talking about the Stanley Cup Champions Anaheim Ducks, ehh??
Truth be told, you really need more than one night in LA. Nevertheless, let's have a go:
Providence: One of my favorite restaurants. Michael Cimarusti knows how to cook fish.
Water Grill: Another favorite, particularly in downtown LA. David LeFevre is starting to come into his own since Cimarusti left to start Providence.
Ciudad: Nuevo Latino cuisine. Owned by the Two Hot Tamales, Mary Sue Milliken & Susan Feniger. This is one of my "fun" restaurants. Also in downtown LA.
Blue Velvet: Recently opened, just near downtown LA. Kris Morningstar (Patina, Meson G) is the executive chef.
Cut: Wolfgang Puck's steakhouse in Beverly Hills, nearby Spago. Richard Meier-designed room.
Craft: Tom Colicchio place in Century City. Good food very well-prepared. The portions are huge, family-style.
Pizzeria Mozza/Osteria Mozza: Nancy Silverton & Mario Batali are partners in these very popular places.
If you have any questions, well, you know what to do, Neil ...
