We went to this sort of speakeasy place (it has an unmarked door). It has a reaction system (fortunately they were able to accommodate us with just a 45 minute wait).
For our waiting the bartender gave us free apple martinis.
For main drinks, got an old fashion with just regular sugar (not simple), and a custom drink that had whisky, chocolate, and cherrry flavors.
Also, you’re supposed to write on anything in the restaurant. Wrote Trancienzo.
