I think your well on your way to a workable prototype.

Some things I would add:

Landing Page (http://gustatio.us/):

1. Needs some kind of call to action (what do I do when I land here)

2. Add signup/Login Info to homepage.

3. Maybe add some of the latest reviews to your home page.

4. Site Search

Location Pages:

1. Address / Contact Info?

Reviews:

1. List the username and time-stamp when/who made review.

Also, try cleaning up the URLs to use meaningful permalinks. EX: /categories/taco
