Middle Island sushi lovers will soon have their wish granted.

Good Wok, the small Chinese restaurant in the King Kullen shopping center on Middle Country Road, is expanding both in menu and in size.

The longtime Middle Island eatery will soon be serving traditional sushi and sashimi, making it the hamlet’s only eatery with the Japanese fare.

The mostly takeout restaurant has taken over the space next door, which has been vacant since Rental City left five years ago.

While only a handful of tables seating a total of 16 customers can currently squeeze into Good Wok, the restaurant will soon  seat 66, the maximum number the shopping center allows.

The Lin family opened Good Wok two decades ago and has offered Chinese fare only, said co-owner Ben Lin. The success of his brother’s sushi restaurant on Route 112 in Medford, Golden Star, which is owned and operated independently of Good Wok, inspired he and his father to begin offering sushi in their establishment.

“My brother’s restaurant is doing very well so we wanted to bring sushi here,” Mr. Lin said.

The new menu will include sushi items and Asian fish dishes, and the beverage menu will soon boast beer and wine. Additional servers and chefs will be hired to accommodate for the expanded services.

Mr. Lin expects business to be good. People in the area seem to be big fans of sushi, he said, and the tiny rolls can be hard to come by.

“There’s no sushi around here for miles,” he said.

There are restaurants that serve sushi five miles away in Rocky Point and seven miles away in Medford. But Middle Islanders now have an option in their backyard.

Mr. Lin said the fact that so many food establishments nearby have scarce seating will also prove to be a boon for business.

And he’s already secured popularity in the area.

“A lot of people come here and like it,” he said.

Construction has been underway for about two months, during which time the restaurant remained open, receiving take-out orders only.

“I’m doing [the construction] myself, so it’s been going slow,” Mr. Lin, wearing a tool belt, said with a laugh.

The renovated restaurant will be a bit fancier, he said, with its large paintings, wood-paneled walls and sparkly lampshades.

Most of the work is finished. Next up is installing equipment in the kitchen and moving the furniture in.

“Almost done!” Mr. Lin said.
