My company did what must have been a custom City Market Tour, as no way could it have ben 29 bucks. It was a cool team building style activity where we did beer tasting, loads of food tastings, and a big get togehter with food and booze at the end.
needless to say it was completely awesome. I forget the guides that were running it (there were several very nice young women), but they were terrific. Overall a fun corporate activity - and probably for anything really. I got their card as Im going to have them put on a pub crawl for my wife's second '21st' birthday :)
