Okay, how about if your "closed" you let someone know your closed???
Leave a message on the voicemail, post something on your website, let Yelp know, smoke signals, anything....otherwise someone will drive expecting a decent slice of pizza and low and behold- denied!!!
Also one of my pet peeves is when a restaurant is going to close, why don't you, as a restaurant owner, say your closing? Telling everyone your "closed for renovations" while literally the place is cleared out accomplishes what?
It's obvious the place is closed, thus the posting on the door, and there isn't one item left of the original place. Hopefully another great pizza place will be moving in.....only one can hope
