The owners of Katch Restaurant in Tanner Park are switching things up this summer.

The beachside concession will be transformed into a sit-down restaurant called Sully’s Wharf, something that has been missing in the area.

“We wanted to re-invent ourselves,” said Sully’s Wharf’s co-owner Dave Chiarella. “There aren’t many full-service restaurants nearby where you can eat right on the bay.”

Chiarella says him and his team also wanted to differentiate the Copiague location from their Katch Restaurant at Lindenhurst’s Venetian Shores.

Last May, Katch opened both locations in the old Beach Hut sites in each South Shore park.

Sully’s Wharf will have a much different vibe than Katch of Venetian Shores, says Chiarella.

“If people want a nice, relaxing evening you’ll go down to Tanner Park, and if they want to rock out to bands they can go to Venetian,” he said.

The new Sully’s Wharf will now feature indoor and outdoor seating.

The owners turned the counters, which were used for concessions, and made a 30-seat bar out of it. There will also be tables that will fit an extra 30 patrons.

“You’ll be able to sit at the bar, eat, and watch the sunset,” said Chiarella.

The menu will be seafood-based with American options and will have specials throughout the week.

A Caribbean Lobster Bake is being planned every Sunday, which is a day filled with Caribbean music and seafood.

In addition to being a full-service restaurant, Sully’s Wharf can now be used as a place to host private events, said the owners.

Sully’s Wharf will be opening on Memorial Day weekend beginning on Friday, May 24, from noon to 9:30 p.m.
