32. The Old Shillelagh
Address: 349 Monroe St.
What's a shillelagh? Remember Monk from Gangs of New York? He carried a walking stick (or club) with a knot at the end. You might need one of these if you beef with the regulars. Amateurs are advised not to fuck with Detroit natives, as that city is one of the realest. Make peace early with a round of Jameson and melt into the background at this bar, a staple since 1975, now seeing its third generation of owners.
