Just a note on the descriptions field. The original idea was this to be a factual description, not really personalised by opinion. So, for the B&C "Bull and Castle - German style beerhall with a strong emphasis on Irish beer. Often the first pub to get new releases from Irish breweries. The ground floor also houses a steakhouse." would fit, in my opinion. It's not so much changing the app, but getting the content updated, and that is a community effort. We shied away from a reviews module originally as we felt there were other sites doing that type of thing. Plus, locations may come and go, and we remove locations if they drop Irish microbrewed beer, so people might be pissed off if their reviews also disappear.
On the images, the option has always been there to upload an image, but again, it needs the Beoir community to provide them. If they are there, I'm sure Andrew can do something with them!
