here are a few eateries i'd recommend...
Tito's Tacos
Johnnie's Pastrami Restaurant
this place is all about their pastrami sandwich and their chill cheese fries are pretty damn good too.
SugarFISH - Welcome to sugarFISH!
a very different spin on your usual sushi bar... fish is extremely fresh and the rice is served slightly warm to bring out the fish's full flavor, which is the traditional way. The best deals here just going with the "trust me" or "trust me lite."
Paco's Taco
(the Centinela Ave locations is the only one you should go to!)
TENDERGREENSFOOD
(boomana, if you can, you need to try the happy vegan salad -- it's my favorite and absolutely amazingly good!)
Versailles Cuban Restaurant
(just get the garlic chicken and the culver city location is the best one i've been to, and i've been to a few.)
Samosa House
it's set-up like panda express, but it's vegetarian only india food -- reasonably cheap and really good.)
Phillips Barbecue
1517 Centinela Ave
Inglewood, CA 90302
(310) 412-7135
no website, no place to sit, but the Pork ribs are the best I've had in LA.
i could probably add a ton more as within 20 to 30 miles of LAX are some fantastic restaurants, but i tried to stick with the relatively inexpensive, reasonably quick and consistently good eats somewhat near by the hotel.
