Are you going to be open on 12-25

No. They are not open on Christmas if it falls on a Monday. They are open on all other holidays if they fall on a Monday.

I don't know, I was only there once.. call them up and ask

You would have to call them . don't know

I was told by a vendor that they are open every Monday, regardless of what holiday might fall on that day.

Yes

I don't know because I don't work there, call them.
