I notice that there are very few entries in the review section. It seems that we should have more, but after submitting my first I think I can understand why there aren't.

First of all, can we please get UBB code enabled? It's tough to make a comprehensive review when you can't do lists, formatting, etc.

The process itself is counter-intuitive; I had to go back and look a couple of times to figure out how to write a review. Clicking that I want to write my own takes me to a list of other people's reviews with some very tiny text above it telling me to clck there if I want to make my own.

In the case of restaurants, the list of cuisine types is pretty long but doesn't come close to including all options (I wanted "Catalan"). I think it would be better to have a very short list of less than eight or ten big categories and then let people categorize it on their own. I can see people getting to this step, not knowing what to choose, and then bailing.

High-bit characters in names and addresses are getting eaten. The restaurant I reviewed, Mastroqué, came out as Mastroqu. There was no way to go back and change this - once it was entered, it was stuck. So I had to go back and create another entry. I noticed on the initial list that I'm not the first person this has happened to; there are multiple entries, some missing letters, for other places as well.

The link field for a map is mangling the URL as well. I pasted the following link:
http://www.bcn.es/cgi-guia/guiamap4/...ero=29&calle2=
and this is what came out of the other end:
http://www.bcn.es/cgiguia/guiamap4/c...ero=29&calle2=

it ate the dashes from the URL, leading to a broken link. There is no way to go back and fix it, so it will have to stay broken.
