One of my favourite places to study at. Their Spanish moon is sooo good. I also like their drinks here 💜
Every time I come here the coffee is amazing, especially the iced cappuccino! The atmosphere is definitely great for sitting and talking to a bunch of friends!
What started as a rainy, gloomy day turned into one of the coziest little experiences at Mongo’s Coffee Roastery & Lounge on Long Island. ☕🌧️ The space has such a cool industrial vibe — warm, inviting, and full of character without trying too hard. The service was genuinely kind and friendly, which made the whole atmosphere feel even more welcoming from the moment we walked in. Our table was filled with cappuccinos, flat whites, black coffees, teas, pastries, and broccoli quiche… Good coffee, cozy energy, lovely people, and a place that somehow makes a rainy day feel special. Definitely a spot worth stopping by.
Coffee first shop, with great sandwiches and baked goods to compliment their locally roasted beans. Thoughtful and attentive staff made us feel welcome, and it was clear from the presentation and flavor that they really care about the coffee. House made pumpkin syrup was amazing, and whole milk flat white was perfectly balanced with rich coffee flavor. We got a gluten free and regular version of the “downtown” sandwich, delicious and fresh. Highly recommend, family atmosphere with plenty of seating and WiFi, several people were working on laptops.
Second time coming here and this time with my friend and our dogs! We loved it so much. The food and coffee is great and it’s awesome that they are so dog friendly. We will definitely be back!
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.
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.
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 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…
I’m a regular of Mongos – it’s hard to find a café that you can both socialize and work/study at. As long as I’m prepared with noise cancelling headphones for roasting/rush times, I can spend anywhere from one to multiple hours here, ordering several different well-made drinks with housemade, seasonal syrups and good food. Over time I have seen the baristas, who are always sweet and hard-working, get better at their craft. The reason I’m leaving a review this time is because they recently added a fill-your-own water station with reusable dishware, allowing customers to stop bugging the baristas during rush and most importantly limit the amount of plastic waste from the previous-disposable cups. For myself and my peers, sustainability has become more and more important in deciding where to spend our dollars. I largely appreciate this seemingly-small change, especially knowing that it adds more labor (washing dishes) for the workers. To the owners -- know that these factors are always noted, and that sustainability will continue to be an important factor for future purchases as more cafes pop up on the island. Looking forward to the day you can offer reusable cups for iced drinks :)
