Every weekend I drive from Palm Springs to West LA, and the first hour is just a slice of hell on the I-10. I go through Banning, Beaumont, Calimesa, Redlands, Loma Linda, Rialto, and Ontario.
Other than Redlands, which seems ok except for the smog, the entire trip is just Mad-Max. Once I get to the Pomona area, I know where some good places are, but everything before that is just a vague wasteland. I generally end up eating at the wonderful Chinese places in Monterey Park.
Are there any hidden jewels on that first hour of the I-10?
I am a true omnivore. If there is a great truck-stop along the way, that would be super-cool. It doesn't have to be trendy or fancy. Just really good.
