The sign said they were opening tomorrow.
The person who signed the letter said his secretary made a mistake. I'm not sure why it wasn't fixed yet, (or why he signed it without reading it.)
I saw the letter on מוצ״ש. I asked one of my kids to go and snap a shot of it before it's replaced. My kids came back and said the place is open.
When I went out for a walk with DW at around midnight, we passed by, letter was corrected (attached), and Rabbi Weinfeld was sitting inside talking to someone (presumably owner).
