What is Worth Choosing

For New York area patrons, especially those searching for an authentic, high-quality, and versatile breakfast or lunch spot on Long Island, Bagel Boss of Roslyn is an excellent choice. What is most worth choosing here is to experience their unique and signature creation: the Flagel. Topped with cream cheese or used as the foundation for an egg sandwich, the Flagel is a culinary experience specific to Bagel Boss that customers often "fight over."

For a classic morning meal, ordering any Bagel or Flagel with a Schmear or an Egg Sandwich (like the popular toasted "everything egg bagel with eggs and mushrooms") is highly recommended. The service is fast and friendly, even when busy, ensuring you can grab your morning fuel efficiently.

For lunch or weekend needs, exploring their Smoked Fish Medley Platter ($23.00) or one of the house-made salads, like the Tuna Platter ($9.99), provides an authentic Kosher deli experience. Finally, remember to take the advice of the regulars: "ALWAYS ask about the lunch specials" for a delicious and well-priced midday option. Bagel Boss is a comprehensive establishment that truly caters to all occasions, from a simple grab-and-go coffee to full event catering.

I love bagel, boss, very convenient. It has the best parking lot and they are always on point with the service. Molly Is the greatest!!! Always super friendly with a big smile and I can’t remember all of their names, but everybody is amazing. Sometimes in everything, egg bagel, toasted with eggs and mushrooms, hits the spot in the morning

Flagels...What are they? You need to visit a Bagel Boss to experience this creation; one of their specialties.Can you get this in Chicago, Boston, Miami, LA, or even Manhattan? Only if they have a Bagel Boss location (it's a Long Island thing).Imagine a Bagel... thinner and less chewy, coated with your favorite toppings on each side - it's practically like getting two top halves. We actually fight over these!It's a must try. And always, ALWAYS ask about the lunch specials - they are not to be missed.

We had the everything bagel with scallion cream cheese and an everything bagel with egg/tuna salad. Everything was wonderful and delicious!

Bagel Boss in Roslyn, on Willis Ave is a wonderful place with bagels and salads and the nicest and most helpful staff. I go there frequently or order online for delivery for breakfast or lunch or something to save for dinner later in the day. Today there was an error in my delivery order and the staff bent over backwards to make things right. They sent one of their own staff (i.e., not DoorDash) to bring me the corrected order, plus a box of delicious cookies as a bonus! I can't recommend Bagel Boss in Roslyn more highly!
July 26 · Sheri Weisz
Food is great but staff is horrible. They act like they are doing you a favor when taking your order. They often tell you to wait in a very direct tone if you need a cup or paper plate. This is not my first time experiencing this type of attitude towards the customers, and this is why I decided to write this review. Food is good but staff is what caused me now to ever come back to this place. hopefully something will change in the future
