Teriyaki Express at the Everett Mall…closed?

I went to pick up something for dinner last night, and they were closed, looked like the space was being gutted. I guess I should have seen it coming, since the other food places next to it had closed. Does anybody know if this is a permanent closure, or if they will be back once the mall is remodeled? I would totally understand if they decided to retire, I have been eating their food since I was a kid (since the 90’s!), but I’m sad I didn’t get a chance to say goodbye/thank you. Their fried rice is sooooo good, one of my fave teriyaki spots, for sure. 😢
