That means he will roast the lamb for the family on the American Easter celebration on March 31, and, since the Greek Orthodox Church celebrates Easter at a different time, he'll roast a lamb for the church on May 5.
Michael isn't the only one sad about Best of Crete's departure.
Management will also be sorry to see the restaurant close after nearly three decades, said Lisa McCracken, Town Center Mall spokeswoman.
"We're really sad to see them go," she said. "They've been with us for a long time.
"They've always been an outstanding addition to our food court and a popular destination for everyone," McCracken added.
The restaurant's lease was up for renewal when Michael decided it was time for him to make a change so he could relax and spend more time enjoying life, he said.
"The mall has always been good to us," he said. "They would love for us to stay, but it's just time.
"We've done very well here and it's time for us to step out while we're on top."
"We came in first class and we'll go out first class," she said with a smile.
Joe Zak, 66, of Charleston, hopes the family decides to open another location somewhere in the city. Zak, a Charleston attorney, has been coming to the restaurant about three times a week for the entire time Best of Crete has been open, he said.
"It's really wonderful to get a home-cooked meal instead of the usual fast food," Zak said. "And their desserts are outstanding."
On Thursday, Zak was enjoying some chicken and green beans from the restaurant.
He hopes the family will decide to open a restaurant in a location convenient enough for him to continue to go three days a week, he said.
"But if it's not that convenient, then I'll still probably go two days a week," he said between bites.
Tim Yianne, of Charleston, knows the Birurakis family well. He not only eats at the establishment often, he also worked there as a youngster.
"I started working here in seventh grade," Yianne said. "And my wife Carri worked here when she was in high school."
Yianne said that Joann was like a "second mother to him."
"She taught us responsibility and helped us develop our work ethic," Yianne, a local attorney said.
"It's hard to believe they're leaving the mall," he added.
Michael is a longtime Charleston resident. He graduated from Stonewall Jackson High School on the city's West Side in 1979.
Michael also has the distinction of having played football for both West Virginia University and Marshall University -- even though he never played one down in high school.
"I had to work in high school," he said.
He landed a spot on the Mountaineer squad in 1980 as an offensive lineman. However, he didn't score a scholarship, and ultimately opted to transfer to Marshall University after two years. The university gave him a scholarship he needed to pay for his education.
