Innovative, custom displays and the plethora of unique decor available really lend a certain atmosphere to the place, even before you enter. The cages with animals in them were clean. They had a few unusual species. But many of the cages did not have animals in them.
Something I found odd was the outside, from the outside of the store it almost looks like it could be a trinket shop to the casual observer, there is nothing that immediately stands out that says its primary function inside is "pet shop".
A definite down side is the smell. Very odd and it permeates the entire space. If that were reduced it would be 4 stars easily.
If Yelp allowed half stars I would probably give it 3.5.
