The Chas.

The Chas. is a Smithtown steakhouse with a business-casual dress code, $$$ pricing, and evening hours throughout the week. The draw is direct: a steakhouse menu led by signature dishes such as Crispy Rice with Spicy Tuna, USDA Prime Dry-Aged Porterhouse, Wagyu Pigs in a Blanket, Beef Wellington, and Lobster & Crab Cake. That combination gives the restaurant a clear identity for diners who want a dinner-oriented steakhouse experience rather than a casual all-day stop.

The Chas. is worth considering if the goal is a steakhouse dinner in Smithtown. Its profile is centered on dinner hours, $$$ pricing, and a business-casual dress code, so the planning starts with the occasion, the appetite, and the expected pace of an evening meal. For diners comparing other options, Gallaghers, Lambs Club, La Tête d’Or, Crane Club, and Carne Mare are useful broader dining references.

A Smithtown steakhouse with signature dishes

The clearest reason to book The Chas. is its steakhouse focus and its confirmed list of signature choices. Chef/owner Mark Serrantino’s menu includes USDA Prime Dry-Aged Porterhouse, Beef Wellington, Lobster & Crab Cake, Wagyu Pigs in a Blanket, and Crispy Rice with Spicy Tuna. The list matters because it gives the menu shape before a diner ever arrives: beef is central, but the additional confirmed dishes broaden the decision beyond a single steak order.

First-timers can use that signature list as the decision map. Start with one or two confirmed signatures if the table wants to sample more than one side of the menu, then decide whether the meal should center on the USDA Prime Dry-Aged Porterhouse, Beef Wellington, or Lobster & Crab Cake. Crispy Rice with Spicy Tuna and Wagyu Pigs in a Blanket also give the meal a broader starting point before choosing a main focus. For diners comparing beyond Smithtown, Gallaghers, Lambs Club, La Tête d’Or, Crane Club, and Carne Mare offer additional points of comparison.

Plan around evening hours

The details support a dinner-focused steakhouse rather than a daytime restaurant: Monday through Thursday hours are 5:00 PM to 10:00 PM, Friday and Saturday run 5:00 PM to 11:00 PM, and Sunday runs 4:00 PM to 9:00 PM. With a business-casual dress code and $$$ pricing, The Chas. is best framed as an evening steakhouse choice in Smithtown. Those hours also make the restaurant easier to evaluate on its own terms: it is positioned around dinner service, not lunch, brunch, or late-night flexibility.

The trust signal here is not an award claim or a ranking; none is in the available data. The grounded information is simpler: The Chas. is a Smithtown steakhouse from chef/owner Mark Serrantino, with a set of named signature dishes and consistent evening hours across the week. That is enough to understand the basic promise without stretching beyond the facts: a Smithtown steakhouse, a defined dinner window, and a menu anchored by recognizable steakhouse signatures.

Compare other dining in Smithtown before choosing. If the priority is a steakhouse dinner at The Chas. plan around the posted evening schedule and the business-casual dress code. The best fit is a diner or group that wants the structure of a $$$ steakhouse meal and is choosing from the known signatures rather than looking for an all-purpose neighborhood restaurant.
