Quite a stat.
“Nearly one in every two buildings boasts a coffee shop, from Starbucks to local brands such as Caffe Bene and Angel-in-us Coffee. Despite the existence of shops a mere 70 meters (yards) apart, it can still be hard to find a seat on some evenings even though a cup can cost more than a meal.”
I never thought I would say anything about coffee was problematic. Interestingly enough, though, it can be hard as hell to find just a regular cup of brewed coffee.
