Second Request - Please help me from starving in Ontario!
There are a few decent places out in the boonies if you know where to look. Service comes and goes, but the food is always well priced and decent:
1371 S East End Ave
Pomona, CA 91766
510 Foothill Blvd.
Pomona, CA 91767
Or for the "college town" feel you can always go to Claremont and try the Press or Hero's for burgers.
These are pretty pathetic suggestions. Mine won't be much better though.
Victoria Gardens is only a few miles up I-15. It has a Yardhouse Brewpub. Hundreds of beers on tap and I think the food is decent.
