Travel Technology - Yelps equivalents in Europe and the UK?

What are the best Yelp equivalents in Europe and the UK?

I'm especially interested in:

England
Austria
Czech Republic
Germany

There is Yelp for London and major cities in the UK.

Same for Germany and Austria. I don't know if there is something better

You may want to give Qype a try. I've only used it once or twice but it was pretty good.
