Recommend me some Wiki software

I’m thinking about setting up a website, a wiki, to allow my friends and I to create and manage a list of restaurants that we have tried or would like to try. Location, style, pricing, reviews.

I’ve heard that setting up and running a wiki is pretty simple, but when I got to look for software, there is a large selection of them.

Does anyone have a version that they use and like? Ideally, it would have a blog or messageboard like comments area, but that’s very secondary to the basic ability to add text, link to other pages, and let a number of people access/update it online.

(shameless bump, in the hopes that someone has a recommendation)

At work we use MoinMoin and it works very well. Unfortunately it’s written in Python and that isn’t supported everywhere.
