My money would be on the guy who erected the plastic signage……..
Recently Ger sent me a picture from his phone of the North Square restaurant and said it would be perfect for an entry here.
I stood looking at the building for a good while and still did not spot the issue.
Very fancy ‘N’ with scrolls on three of the four corners.
The plastic ‘N’ on the wall sign is not the same as the ‘N’ in the menu – unless you turn it upside down.
