Urbanspoon.com is a comprehensive online restaurant review site that pulls together user-written reviews with information culled from blog posts, Twitter and professional reviews.
The free Urbanspoon BlackBerry app offers a gateway to that information, but with a twist: Instead of searching for particular restaurants, Urbanspoon presents a slot-machine-like suggestion engine.
Three wheels for geographic area, type of food and cost spin to present random combinations -- and a restaurant that fits those criteria. You can go for broke and spin all three, or you can "lock" each wheel independently, searching for, say, Indian restaurants in your area regardless of price, or any affordable restaurant in a specific part of whatever town you happen to be in.
It's a great way to find restaurants in new cities where you have nothing on which to base a decision -- and to rediscover familiar towns you've been to a hundred times.
