1) Logo text is a link to hompeage, but the image is not - I kept trying to click the image
2) Login link doesn't quite fit the design, needs a bit more pop
3) Plan comparison page doesn't do a good job of selling me on the paid version - something like a comparison table that makes the benefits of the paid version more obvious, or highlight of the additional features would be better. The simple lists of features you have for each plan type now doesn't cut it.
4)The tour is good, but a link to the live site in the tour (or another live site, maybe your first few customers?) wold be nice so I can actually see a live one in action.
5)An offer to sweeten your paid plans (or an additional package) would be to submit the restaurants to places like yelp, urbanspoon, yahoo directory, etc so they can get inbound links across the web and their page can be more discoverable.
LOVE the idea though, and the design rocks. Simple is better in this case. Good luck with Cilantro!
