The fixed bottom footer could use a bit more contrast. When the white text from the main body slides over it, it gets garbled and messy looking. Also, there feels like too much space between each section when I scroll down.
I like that I can see results without having to sign in with Facebook. It lets me try out the service before I commit.
The color scheme is cheerful, but a bit too harsh. The nav elements within the results also lack contrast.
The animation on the place name on hover is neat the first time, but annoying every time after. The tiles are just jumping around all over when I move my mouse.
Filtering by category could be faster, but I like that it does it via ajax and stays on the same page.
Overall, good job! Best of luck
