Ever since the Westfield Century City Shopping Center’s glitzy and expensive makeover, restaurant news has been overshadowed by the big names (think Eataly).  But, as they always have, things change very suddenly in this mercurial food scene.  Here’s a what I observed recently…  On the second floor near Eataly, a new Sichuan charmer promising “flashy surroundings & theatrical servers“, HaiDiLao Hot Pot, is on the way.  Mezza Garden has closed up shop on the first floor.  And one of the last empty spaces in the food court will soon be home to Shuck House, a seafood and oyster bar that plans on opening in December.
