Dinner at the Westin LAX or is there any good food at the airport itself?
There is a $5 red Ocean Express trolly from your hotel that will take you to close by Manhattan Beach were you will find better food. I like Petros, for upscale Greek food or Darren's for good California Bistro food also many more casual restaurants.

Bilal Restaurant in the 7-11 strip mall on Manchester, about a 7 minute cab hop has unbelieveably delicious Indian/Pakistani/Halal food. The Friday Birani is always sold out by noon. Great ethic experience in food/company plus a well lit location - just cab it home as well, this is not a "walky" neighborhood.
