Wash your hands!
Next week, when I visit an “on-premises” (jargon for a restaurant/pub/bar/tavern etc.), on a burger-and-beer adventure, the first thing that I will do is find the restroom and wash my hands. That is only after I have secured a seat at the bar, of course.
This may sound ritualistic but there is a method to my madness. Over twenty years of being a "professional barfly” (journalist covering the beer business) there is one thing that has never changed. Simply put, if the restroom is clean and echoes the hospitality of the premises then it can be presumed that there is a relatively good chance that there is a “beer clean” glass behind the bar and a bartender who knows how to pour two fingers of head.
Yes, I will admit that two or three of the historic watering holes on the island of Manhattan have rather primitively maintained Water Closets. On the other hand a good number of the less pretentious establishments maintain quite pleasant lavatories. No surprise to this barfly, the ambiance, service and the quality of the food and drink far exceeded the modest first impression.
Try it yourself! In fact I will buy you a draft brew of your choice at the place you find that has a stinker for a wash room and a “beer clean” glass behind the bar and a bartender who knows how to pour two fingers of head.
