"The site is a pimped-upwhatsonwhen, offering information on events in Europe. You can search by date or drill down by destination or interest using the simple navigation panel on the right. The information is thorough and there are links to the event website, but the content is quite as extensive as its afore-mentioned rival." - http://www.timesonline.co.uk/tol/travel/news/article6804027.ece?token=null&offset=12&page=2
