If you're ever on the way to or from Vegas, or simply out near Riverside and looking for a good Indian meal, check out Masala House. It's a small Indian grocery with hot food. I'm not entirely sure what I got (a samosa, chana masala....), but it was great! Only downside is that they use Styrofoam - next time I'll bring my own container.
