I don't know much about birds, and I think that dogs and cats ought to be acquired through animal shelters, so I'll just talk about the reptile and fish departments.
The fish room is OK, I guess. More than half of the coral tanks are inadequately lit, some so poorly lit that the photosynthetic livestock in it will likely bleach upon being introduced to a proper tank. In other words, corals purchased out of those tanks will likely die. Prices on aquatic livestock in general is high.
Livestock in the reptile department is mediocre. Enclosures weren't really dirty, but not really clean either. "New arrivals - not for sale" are housed next to animals that are for sale, which means that diseases carried by the unquarantined animals will pass to others in the store (mites travel pretty quickly).
Though there is a sign claiming that they buy from local breeders to ensure quality, some of the animals (water dragons, russian tortoises, collared lizards) are certainly wild-caught without being labeled as such. The rainbow boas there today were really being mistreated -- kept in screen top tanks on aspen bedding with undersized moist hides containing bone dry sphagnum. They won't make it long under those conditions.
