I've only been there once, but I remember really liking Rizzo's Pizza on Sepulveda (not far from El Paso Cantina)...
Also - Lomeli's in Gardena...yum!
Anyways, it's good, especially the All-You-Can-Eat pizza/pasta/breadsticks on Monday nights, though I think it may be like $10 now or something. It was $7 back in the day. Still, really good stuff.
Rizzo's breadsticks are awesome, and their salads are good too.
I agree about Lomeli's. It is a huge favorite of my wife... very small place thoug in a strip mall, so at times you have to wait. Worth the wait.
I also like the pizza at Hank's Pizza in South Torrance near PCH and Hawthorne. It has a sweet crust that is really great.
