My husband and I went on this tour for our trip to Brussels. The tour guide Mark was absolutely amazing. He was very fun and informative on all the different beers that we were trying. We were in a group of 6 people and I find that it was a perfect size group. I highly recommend that anyone that books this tour eat prior to the tour starting as to you will be drinking some strong beer and will be slightly intoxicated by the end. I would recommend this tour for anyone that wants to enjoy the different Belgium beers and have a great time doing it.
