Is WordPress right for me?

I am so, so confused. We publish a city entertainment guide and we want to build a website to go with it. The printed guide covers:
i) Restaurants & Bars listings ii) A What’s On Agenda iii) Articles
iv) Shops – And lots more. If you want to see a site that is pretty much what we want to be like have a look at http://www.viewlondon.com
We need a database driven site, one that users can use to search for restaurants, bars, shops, events for by type, area, price, date, etc etc. Plus we want be able to add new content (eg. restaurants) every month easily and quickly. Is wordpress really what we need to be using for a site this size? We just found out that the team we hired to build our site are using WordPress and frpom what I’ve read it perhaps isn’t the right way to go. Yes, you can perhapos make it do what we want, but is it ideal? PLEASE ADVISE!
