Mongo's Coffee Roastery & Lounge

Coffee and my laptop , the perfect Sunday afternoon vibe. If I had to nitpick, I wish it came in a ceramic cup with latte art instead of paper. But I’m guessing they ran out of mugs since it’s such a busy afternoon.

Mongo’s is a great go-to for espresso enthusiasts on Long Island.

The espresso is rich and tasty, and all baristas are very well trained.

Baked goods are ok to great. I have not had their sandwiches or other items.

Space is limited on a weekend, especially if you are looking for a chair and table as most seating is lounge chair, high top, or couch.

This place lives up to the hype. Delicious quiches. I truly appreciated that they were vegetarian and didn't have to worry about ham. Brown butter miso latte did not disappoint, I asked to make it less sweet and it was so perfect. Atmosphere was lovely. I will have to make the trip out here more often to treat myself! I made sure to get a bag of Guatemalan coffee.

Coffee Divine 🥇🥇

Mongo’s is bustling with great vibes & aromas. Feels a bit like a college dorm with adults seeking their caffeine fix.

The leather seats are upscale and the XL wooden tables give off an aura of grandiosity.

But the main appeal is the coffee beans being ground here. One sip and it will beam your inner self up to the cosmos…

Such a cute space, was a little loud while working as they were grinding beans for the coffee but otherwise a great spot and I’ll be back to spend more time here. Iced coffee was flavorful and not bitter. Steak sandwich was actually quite a large meal to finish and I felt so stuffed afterwards.

Favorite local coffee shop near Syosset, great coffee and baked goods, loads of seating to work from, does stay very busy with people working on computers. Lovely environment to sit and work or chat.

Ahhh Mongoes….a roastery with great atmosphere, great food, and best of all, great coffee.

Friendly feel here and busy surroundings…..it’s bustling. When you find a cosy spot and settle in, however, it’s a fun spot to chat, compute, people watch, or….well….lounge.

Gotta love those places that perfectly deliver what they project. As long as it never changes, I’ll keep coming.

Got a hot mocha and an iced latte. Mocha was like warm and pretty meh.. iced latte was more milk and very little coffee. Pretty sad compared to the ratings here. Also took 15 mins to get these.

This has literally become my 2nd home. The coffee choices are impeccable, the staff if very friendly and quick in service, the management and the owners are very responsive. The places is rustic they grind their own coffee been too. If you have not had Mongos Coffee then you are missing something.

A must-visit coffee spot with great vibes and great values!

I absolutely love Mongo's in Syosset. The space is large, comfortable, and has a fantastic atmosphere. The service is consistently friendly and welcoming—they make you feel right at home!

But what really sets them apart IMO is their dedication to offering high-quality, responsible products. Outside of their excellent coffee, I was so impressed with their selection of environmentally-friendly drinks. It’s great to see a coffeehouse stocking options like the Certified B Corp coconut water (like the one pictured!), which shows they care about sustainability and what's in their drinks. It’s refreshing to know you can grab something tasty that’s also made by a company focusing on things like reducing plastic and avoiding nano-plastics.
Whether you're there to work, relax, or just grab a quick, conscious drink, Mongo's delivers on all fronts. Highly recommend!
