The Bareburger franchise at Bay and Dundas has been closed the past few days. I remember seeing a closure for emergency maintenance a couple of weeks ago (but then reopened), then over the weekend they were closed again with a sign up saying they were having difficulties, "please bear with us", now the sign is down but it's still closed with no other indication of what's up. It's still listed on the chain's website though, so maybe it is just ongoing maintenance issues? I had noticed it not being so busy lately, but I thought it was doing reasonably well on weekends at least.
Update: as of Saturday the windows are now papered over.
