'David Rio' is a very popular chai brand in San Francisco, USA.
The aprons were adopted as part of the uniform at Chai Bar, which opened in 2015.

The store also sells three different types of aprons.


The orange of the apron strings also matches the color of the store.
I'd love to visit your store sometime.
