Yelp was the first thing I downloaded when I walked out of the 5th Avenue cube with my new iPhone .... two taps and I had a list of restaurants in midtown narrowed down by affordability.

Priceless (literally) app!

Just downloaded Yelp! and looking foward to testing it out. I have been using iWant for some months now, and I will be surprised if Yelp! is better. iWant's UI is structured well for how I use it -- i.e. to find specific services near me (i'm not interested in writing or even reading that many reviews on my iPhone)
like Yelp!, its a single location finder app that you can use instead of the various apps for specific things (coffee, taxis, bars, etc). It give to the option to view both lists and maps of your results, and the dev says its the only app updates the search results as you move the map to different locations.

It would be ideal if MacWorld would review all the apps that do similar things in one review.
