The Clam Bar @ Alize Brewing

On a second pass through Mattituck, the useful question is where to go when the day becomes a casual seafood night. The Clam Bar @ Alize Brewing is a practical answer: a Mattituck seafood venue with a lively, cozy, rustic feel and an approachable price point of about $30 per person. It suits visitors who want the evening easy, social, and seafood-centered without making the plan feel overly formal.

The description is simple but useful: lively, cozy, and rustic, meaning a casual tone rather than a polished fine-dining setup. Consider it for a relaxed Mattituck seafood stop. Skip it if your plans depend on details that are not confirmed here, such as a specific menu format, seating setup, or special service arrangement.

A clam-bar dinner in Mattituck

The strongest use case is a casual seafood meal in Mattituck, especially later in the day. Hours run Monday–Thursday from 3:00 PM to 9:00 PM, Friday–Saturday from 3:00 PM to 10:00 PM, and Sunday from 12:00 PM to 8:00 PM. The schedule reads as an afternoon-into-evening choice during the week, with a longer Friday and Saturday window and an earlier Sunday start. Instagram also notes late-night or bar hours until 1:00 AM or later, so it can fit some later plans.

Seafood is the confirmed cuisine, and the price is about $30 per person. Beyond that, treat The Clam Bar @ Alize Brewing as a casual Mattituck seafood option rather than assuming specific dishes, service formats, or special menus. Let the category and setting do the work: come because seafood in a lively, cozy, rustic place fits the night, not because any particular item or dining structure has been verified.

Where it works, and where it does not

For explorers using Mattituck as a base, this works when the plan calls for seafood in a lively, cozy, rustic setting. It answers “where can we go for a casual seafood meal?” better than it solves every dining need.

The late-night angle matters: standard listed hours go to 10:00 PM on Friday and Saturday, while Instagram notes late-night or bar hours until 1:00 AM or later. A later visit may fit a different plan from the standard listed dining hours. Go earlier for the clearest confirmed window; consider later only if the bar-hours note fits.
