Reach on 4th has a back door in the alley up some stairs behind the noodle place. It's great for leaving as well as you don't dump out onto 4th which is very busy.
QT in New West in small plaza. Has a back door. Need to inform them if you going in from back.
Lots of parking at the back.
Only slight downside occasionally kitchen staff of neighbour eatery taking their smoke break at the back.
