Oshun closed after service May 21, ending three years of oysters and more at the corner of Washington and East Huron.
The restaurant's lease is up May 30, said chef-owner Jim Guarino, who is going to refocus his efforts on Shango Bistro in University Heights, his first restaurant.
"We're relinquishing the space and not renewing the lease, and I'm going to concentrate 100 percent on Shango," Guarino said. "I've been spread too thin, and it's been hard to keep both places going."
Shango, opened in 2005, "needs some updating," he said, including a new menu he's planning to introduce in June.
The last day of service at Oshun was Sunday. "It's time to close this chapter, unfortunately," Guarino said.
