New Wave Seafood has anchored its stretch of Wantagh Avenue since 1995, half fish market and half restaurant, the kind of place where the person filleting your flounder will also tell you how to cook it. In all that time, the one thing the dining room could not do was pour you a drink. As of this week, that changes: the New York State Liquor Authority has issued the business a full on-premises restaurant license, the first ever recorded at the address.

The license went on the books on August 20 under the company's legal name, and the name is the best part of the paperwork. New Wave Seafood is owned by 4th Generation Seafood Company, and the fourth generation is not a branding flourish. The Marinello family has been selling seafood on Long Island since 1905, a run of more than a century that now sits, quietly, on a state license certificate. Frank Marinello, the fourth of those generations, runs the Wantagh operation today.

What the license actually covers

The new license is a restaurant-class on-premises license, the same class held by full-service restaurants across the Island. It covers liquor, wine and beer served with food in the dining room, and it runs through the end of July 2028 on the standard two-year cycle.

It is also, as far as the state's records reach, a first. The Liquor Authority publishes both its active licenses and its lapsed ones, and neither dataset shows any earlier license at 1847 Wantagh Avenue. Thirty-one years of dinners went out of that kitchen with nothing stronger than a soda beside the plate, on a stretch of Wantagh Avenue that sits a short drive from some of the South Shore's busiest bar rooms.

A fish market that learned to cook

New Wave belongs to a specific Long Island genre: the fish market with tables. The market case up front does the retail trade, the kitchen in back cooks what the case sells, and the menu moves with what came off the boats. It is a format that rewards trust, because the same family that picks the fish at the market stands behind the plate that lands on your table.

The Marinellos have been building that trust longer than nearly anyone in the business. The family traces its seafood trade to 1905, four generations of it, and the Wantagh shop has carried the tradition under the New Wave name for three decades. The shop sits on Wantagh Avenue between Sunrise Highway and Jerusalem Avenue, a corridor that has quietly become one of Nassau's better eating streets, and its dining room has long filled on the strength of the fish alone.

Why a license now

The business has not published its plans for the license, and the paperwork does not say whether the pour will start with a modest beer and wine list or a full bar. What the license class permits is the full range. For a seafood house, the practical difference is easy to picture: a glass of cold white wine beside the fish that was in the market case that morning, or a beer with the fried basket, ordered off a menu instead of gone without.

The timing follows a pattern that has been visible across Nassau County all summer. Family food businesses that spent decades as daytime, counter-service operations have been adding licenses and stretching into full dinner service, because that is where a neighborhood restaurant's margin lives now. Just last week, state records picked up a wine and beer filing from a Massapequa pizzeria that has fed its town since the 1970s. Wantagh's turn arriving via its fish market makes a certain sense: the food was never the missing piece.

What it means for dinner

For readers in Wantagh, Seaford and Bellmore, the practical news is simple. The fish market you already trust for the raw ingredient can now put a proper drink next to the cooked one, which moves it from the lunch-and-early-dinner column into genuine Friday night territory. The license is effective now, though how quickly a bar program appears is up to the Marinellos, and businesses often take a few weeks to stock and staff a pour after the certificate arrives.

The longer arc is the better story. A family that started selling fish when Theodore Roosevelt was president just added the one amenity its Wantagh dining room never had. Very few Long Island food businesses survive four generations. The ones that do tend to know exactly when to change, and by how much.
