This was a great activity. Our tour guide Sarah was terrific at balancing the historical information with fun conversation. She handled everything, so when you arrive at the bars, the guides have a table ready for you and they pick up the beers for you -- no waiting around trying to get the bartender's attention. Very seamless. My two cents would be to develop other and more tours like this that incorporate some local breweries -- Grimm and KCBC are very close together, for example, or maybe you go to the Other Half location at Rockefeller Center plus some nearby bars. But obviously it's hard to beat the Stone Street area for density of bars and American history.
Also, I went with my adult son. The drop-down on "Who was with you?" doesn't have that option so I put "Friends."
