We have a sort of mall with a few bars and the husband and I have been doing the world's slowest bar crawl, trying all of them. I've ordered a whiskey sour at each.
One asked if I wanted egg white and made an awesome shaken one.
One mixed whiskey and sour mix just stirred, barely.
One was expensive but pretty good.
One used real lemon and good Japanese whiskey but again just stirred what the heck?
I literally had one bartender tell me they were out of sour mix and didn't know how to make one.
