Jimmy’s Diner in Mastic is the definition of a classic hometown diner: welcoming, affordable, and consistently satisfying. It’s the kind of place where you can grab breakfast any time of day, sit in a cozy booth, and enjoy food that tastes like it came from your own kitchen. The ambiance is relaxed and family-friendly, with bright lighting, friendly servers, and that familiar diner hum of coffee cups, sizzling griddles, and conversation.

The menu is long, but start with the pancakes or French toast, both fluffy, generously sized, and ideal with a side of bacon or sausage. The omelets are another highlight — packed with ingredients, perfectly cooked, and served with toast or home fries that are golden and crisp. If you prefer lunch or dinner, Jimmy’s has you covered. The burgers are juicy and reliable, and the club sandwiches are stacked tall with fresh ingredients. For comfort food fans, try the open-faced turkey sandwich or a plate of meatloaf, served with mashed potatoes and gravy.

Sides are plentiful and portion sizes are hearty, so come hungry. Kids have plenty of choices as well, and the coffee is always hot, fresh, and constantly refilled. Jimmy’s also offers milkshakes, iced tea, and fountain drinks for that classic diner feel.

Service is quick and attentive, even during weekend breakfast rush. Whether you’re dining in, grabbing takeout, or stopping by for a late-night bite, Jimmy’s Diner offers dependable quality and that nostalgic diner comfort you can’t fake.
