I commute from West LA to Long Beach a few times a week and often times, I try to time it around lunch so I can stop somewhere along the way. The problem is that I'm starting to exhaust my "usual suspects" list of places to eat and would gladly welcome other suggestions.
Right now, I tend to hit up either:
Jasmine Market (Culver City, Washington/Culver exit)
(Tito's is right there too)
Santouka (Mar Vista, Venice exit)
In the past, I've also done:
Al Watan (Hawthorne, Rosecrans exit)
Gardena Ramen + Shinsengumi Hakata Ramen (Western exit)
The main criteria is that the food be 1) relatively fast, 2) moderately priced (or cheap!) and 3) within 5 minutes of a 405 exit. A superior taqueria is most welcome, as is any Asian ethnic places.
