Google Maps guided me down there today. It located inside CalPoly Pomona and is close during the school breaks. Poor management has to update their schedule.
Panda is great when you're hungry I love their chow mein.
They are AWESOME!!! PLUS THEY MAKE MY FOOD FRESH EVERY TIME WITHOUT COMPLAINING!!
If you want Panda Express and you're not a student or work on the Campus... forget it. It's a pain to get to and hard to find if you're not familiar with the campus. Find a off campus location and save yourself the hassle. It's basically a glorified cafeteria.
