I just dined at a nice restaurant that had a set of heavy velvet curtains in a semi-circle around the inside of front door. Not only did it prevent cold blasts to the tables close to the door (I always hate that) it made for a really elegant transitional experience between the dull outside space to the exquisite interior.
