My husband and I are from Orange County and we frequent Pauma. This place is small and has no hotel and absolutely no FRILLS at all. But we LOVE it. We love the simplicity of it. The slot floor is great. Don't expect high limit slots there. They only have a bank of 6 or 8 dollar slots and everything else is quarters or less.
There are many penny machines. The food there is not super high quality but the prices are reasonable. We usually order individual pizzas from Parrot Pizza window and eat it while we are playing. If you are going there for the first time it may be hard to find. It is deep into orange groves and you cannot see it from the highway. Make sure you pay attention to the signs as the roads are dark if you are going at night.
