Zagat is possibly one of the pioneers in user-generated content – long before it became so commonplace on the Web – and I’m interested to learn they’re going mobile with Zagat.mobi. In fact, I’m actually surprised to discover that it wasn’t something they already offered. The free service is compatible with all Web-enabled cellphones, and lists Zagat-approved restaurants, nightlife and hotels in hundreds of US cities plus London, Paris, Tokyo, Vancouver and Toronto.
