well I did the Harpoon tour.
Not impressed at all. Hard to hear the guide - spoke far too fast. Too many 'gags' which failed.
Managed to taste 4 beers - very small samples though - two mouthfulls and that was it.
Whole experience then marred by being totally ignored at the bar for at least 5 minutes. It was not busy (Tuesday at noon!)
I left feeling annoyed.
