Very nice! We toured with Allan (or Al Capone himself possibly hehe) and it was great! It was super informative, and he also answered any additional questions we asked. I loved the way he told a story which made me really feel like I was there in the moment (the greasy Chicago river, yuck!).. Death Alley was probably the spookiest part for me, you can really feel the tragedy experienced there, we toured during the day but I wonder how it would feel at night… all in all though, a worthwhile experience, a nice, not too fast paced walk, and a fun way to explore the city!
