I've been there a bunch of times and it is awesome. The downstairs is a pet store and they have got everything you could need (I don't think the pics on their website even show a fraction of the stuff there), and the upstairs is Herp Heaven. DEFINITELY set up an appointment for the tour! Kevin showed me and my girlfriend around for a good hour I think and you get to see some really cool stuff (more than just snakes).

Also on a side note, stop in at the State Line Pet Supply down the street on Rte 125 for great deals on dog food and toys. I stock up on Candidae for my pooch on every trip, plus NO SALES TAX!
