A new takeout seafood restaurant has opened on the North Shore in Devonshire and it’s already seeing brisk business.The Seaside Grill, below the former Gravity nightclub, specialises in fish dishes including supersized fish sandwiches, and codfish breakfasts on Sundays.Seaside will also deliver, with no minimum order, and its owners said it’s already received numerous lunchtime delivery orders from groups of employees and businesses in town. On Sunday it had 10 deliveries for codfish breakfasts.The restaurant that was in the building closed down about six months ago and a spokesman for the TS Marine Group said they tracked down the landlord and quickly signed a lease on the space.“We sell seafood dinners, dishes with local and foreign fish, fish sandwiches, salads and chicken and hamburgers and fries,” the spokesman said.He said the restaurant also offered a healthier grilled menu, where customers can choose from grilled fish such as wahoo, or even grilled chicken.The fish sandwich, he said, comes with up to half a pound of fish per order.The hours are Monday to Saturday from 11am to 10pm.Seaside is open on Sundays right now just for breakfast but due to demand may open for the afternoon as well.
