I started visiting yelp.com recently.  This site has pretty much changed my dining habits.  It has a far, far better system than citysearch or guidelive or any of the other restaurant/activity review sites out there.  

It is very popular in the SF Bay area and Austin and is growing now in DFW.  I'd highly recommend giving it a try, and you should sign up and add some of your own reviews while you are at it.

Here is my page to see what I think of stuff - if you join up make sure to let me know.

Also I know this post sounds really like when people try to get you to be their "friend" on myspace, I assure you that that isn't my intent...
