I've floated in and out of there for years. It's so-so, but considering it's Fontana, and there aren't many LFS out this way, well... It is what it is.
Prices seem a bit high, the livestock seems as iffy as anyone else's, but they do have more of a selection that some places.
Frankly, I'll go to Jans down in Montclair or - almost exclusively - Total Tropical in Upland. It's not often I stray from either of those two (it's a location thing, for one).
I'll say that the "bad" shops are few and far between these days; lots of stores have popped up where they're REALLY taking care of the customers... IMO it's a great time to be in this hobby!
What kind of corals are you looking for? Might want to ask on the IEMAS club board (or in the club forum here); you never know when someone might be willing to break out the clippers...
