Friday, May 17 will be the finale of Square on Square Chinese restaurant at 1905 Chestnut St. after 17 years, as owner Stephen Yau is moving four blocks away into what is now Szechuan Hunan, at 274 S. 20th St., next door to Audrey Claire at 20th and Spruce Streets.

He expects to reopen as Square on Square on Monday, May 20.

Pang Wong, who opened Szechuan Hunan in 1994, wants to step back from the day-to-day. He owns the building and will become Yau’s landlord.

Yau hosts the All-Star Jazz Trio upstairs on Wednesday nights, and that arrangement will remain after the move.

He plans a grand opening, complete with dragon dance, on June 8.
