These places may be better for lunch.
For dinner, if you like beer and burgers, no brainier is Back Abbey.
A little bit further on the 210 and you can hit up Slaters 50/50 in Rancho Cucamonga. I like the Mac n cheese balls.
Also in Claremont there is nondescript taco place called Petiscos. Fish and pork tacos are good and the elote is as well.
