It takes a while, but you see and learn quite a bit. You get two free beers at the end, and one in the middle of the tour and you get to keep a keen glass. It is on the Big Red Bus hop on hop off tour. It has a pleasant bar/restaurant next to it with soe great micro brews that are worth tasting. This was the last thing we did in five weeks in SA and I leave the country with very pleasant memories, and a little sloshed!
