Takeaway options include chilled and warm sushi, bowls, bao, salad and karaage burgers.
The food is prepared at Momiji restaurant in Victoria Avenue and then transported to the Maria Pl shop.
“We don’t cook in here because there’s no kitchen here, it’s a very small space.”
Miyake believed the shop would also appeal to tourists visiting Whanganui over the summer.
The new outlet opened on Tuesday, November 27.
Assistant manager Sinead Kinchella said the shop’s first day was a busy one.
“Everyone was happy to see a sushi shop in the middle of town, not just on the outskirts,” Kinchella said.
Miyake said he had plenty more ideas about what he wanted to do with the restaurant.
The Grab ‘n’ Go is open Tuesday to Friday, 11.30am-2pm unless the food sells out earlier.
