Most A-frames are there to entice people to visit their premises. The Grapes pub in Newington, Edinburgh does it in their own delightfully original way. Providing you're not pompous, pretentious, a snowflake, vegan, new age, hipster or hamster, then you're most welcome to pop in!
Speaking to a couple of their customers, who are obliged to smoke outside on the pavement, I'd be inclined to include tobacco controllers, healthists and finger pointers. They're definitely not welcome - at any time, for any reason, ever.
No Hipsters or Hamsters A-frame outside The Grapes pub, Newington, Edinburgh. June 2018.
They couldn't care less about comparison sites; TripAdvisor doesn't even list the place - and the last Yelp comment was in 2010. However they do care about Facebook, where reviews are almost always 4 or 5 star and less likely to be paid for or contrived (01).
Love their style! Switched-on Old Skool!
