High Street

You see 'High Street' and hear reference to high street a lot. It refers to a commercial district or street. For example I live on Paddington Street which is two blocks from Marylebone Road which runs parallel to Paddington Street.

Also, Paddington Street intersects with Marylebone High Street. Marylebone High Street is the retail street with the same name as the road. You see that a lot, too.
