All four managers and all eight bartenders will be back, as will the entire kitchen staff and 80 percent of the wait staff, Frisch said.
The Mount Washington Village business community, which has suffered from the loss of foot traffic from the tavern since the fire, is glad to have it back, said Koula Savvakis, president of the Mount Washington Village Merchants' Association.
"All the businesses really felt a difference," she said.
She is also happy to have Mt. Washington Tavern serving oysters at next week's block party to give the relatively new event some extra publicity. The block party, from noon to 6 p.m. on Sept. 30, will also be a fundraiser for the public Mount Washington School, she said.
Frisch said he is planning to have four or five cases of oysters on hand during the fest, which will close Newbury Street and Sulgrave avenues in the Village.
But Savvakis worries about limited parking when the mad rush by the public begins on Nov. 1 to check out Mt. Washington Tavern in its new incarnation.
"I'm sure it's going to be mayhem in the first month," she said.
Frisch said for now, he is only taking reservations for holiday and wedding reception parties of 25 people or more to rent rooms.
He said he has invited Mayor Stephanie Rawlings-Blake to attend a ribbon-cutting ceremony.
"I'm pretty sure she will, because she was there the day of the fire," he said.
Frisch also plans to hold an open bar to thank first responders to the fire, as well as nearby businesses — "for putting up with us," he said.
