Loved it! Got tons of work done today! Very quiet and relaxed place except for the school kids rush at around 11.30 am, but they were all gone in a matter of 20-30 minutes. Staff is nice, coffee is strong, wifi is open (no psw required) though a little slow. Best working experience in a coffee shop so far! read more

A lovely spot for studying and warm vibes with delicious baked goods and fantastic coffee! There's plenty of seating (though not a ton of outlets) and the staff is friendly. The prices are pretty reasonable, as far as coffee goes, and the portions are just right. read more

amazing atmosphere to get a lot of work done! Pretty empty and chill weekday mornings.

It's a bi-level coffee shop with outlets for your electronics, super laid back and chill vibes. All you need is a good book, good company and the coffee is amazing. read more

I liked the place Definitely one of the best coffee places in Brooklyn. Lovely cafe and great atmosphere!! read more

Postmark Cafe is the perfect place to grab a decent cup of joe, plug in, and do your thing. Extremely pleasant staff, outlets galore, and respectful customers, I've now gone here on numerous occasions to get work done. By far, it is the best place around! read more

Excellent neighborhood cafe. Great for vegan chai lovers: their chai doesn't contain honey or dairy products, and you can get it with almond or soy milk. They also carry Alternative Baking Company cookies (yummy and vegan). Plus, all tips go to charity. They pick a new recipient each month and are open to suggestions. Note that they are closed on Sundays. read more

I love this place! It's always so nice and quiet inside, and perfect for getting together with crafty friends. In the back, they've got a nice little room with toys and such, which is perfect for mommies who love coffee! read more

Came here during a massive heat wave to get some work done. Loved the ambience. Had an Ice Coffee and Morning Glory muffin. Coffee was okay, but the Morning Glory muffin was heaven! Came back today to find a zillion baby strollers parked out front. I was worried that I would not find a place to sit and it would be loud with crying babies, but nope. All the babies were downstairs, and although it was packed, I was still able to find a place to sit. This time, had an iced Americano and I fell in love. Great quaint little place, music plays at decently low levels, reliable wi-fi, AC, and delicious coffee--what more could a girl ask for? Oh yeah, and upon entering they were playing 2 of my favorite Shakira songs: Antes de la Seis and Te Necesito. This place just rocks! read more

Just a perfect little spot to enjoy iced coffee and get some typing done is all. (And the barista was super friendly.)

they get four stars because the tables are small and there aren't enough outlets to accommodate everyone, but it's a great space. Employees are nice. Coffee good. Great to get some work done in peace and quiet without distraction read more

Please try the galao! It's amazing! It's Portuguese coffee and it's delicious. I have yet to find a place that serves galao. Hot or cold, it's good. read more

I didn't purchase anything here, and I plan to come back and get a beverage. The review is for their free Friday night comedy shows, starting at 8. They serve wine and beer during these events, and it's a great way to kick off your Friday. read more

Love this place! Great place to study all tips go to charity kind and friendly baristas... and u can even donate a coffee to a med student or nursing student or a tired mom! This place is amazing!!!! read more

Cute place, lots of space, nice people, decent prices. The coffee is not super, but everything else really is. I will go elsewhere for good coffee, but it's one of the best places I have ever found--EVER--to sit and work. It's cozy, free wifi, good vibes, and a great mix of music, if that matters. If you're a freelance-type, I say go on over and make yourself at home. 1/2 star off for the coffee, 1/2 star off for being closed on Sundays. Otherwise, stellar. read more

I like this place. Pretty cool atmosphere. I don't drink coffee, but I typically get either their chai latte or a hot chocolate. Good stuff. Nice spot for co-working. There's a weird little downstairs area that looks like it's set up for kids or something. I think certain groups have meetings in that area on specific days of the week as well. But over all, it's a good place to go if you need to do some coursework or have the need to freelance away from home. The only con is that they're closed on Sundays. read more

Great coffee and a warm and quiet atmosphere. After living around the corner from Postmark for about a year, I'm sorely missing this place as my daily spot. read more

Today was my first time at Postmark and it was so good! Very cute inside and great coffee too. I love that they donate tips to charities. Awesome place! read more

A great place to grab a coffee or pastry, sit down with your laptop and do some work in the morning. The people make you feel like a family or community. I can't comment on the coffee but the pastries are quite good and local. The music is sometimes too loud but nothing a good set of headphones while working won't fix. read more

What a charming, chill spot. They let me sit and work all morning without hassle. They were in fact welcoming! Great cafe.

I give this place 5 stars for the vibe alone.. I was looking for someplace to tuck off and write for the afternoon and this place did not disappoint. Funky, eclectic seating, plus when I arrive several other people were already on the laptops. Perfect for me for this time. read more

Postmark is a unique cafe with a lot of various forms of seating in Brooklyn. The baristas are very friendly here and the overall vibes are very relaxed/cozy. The downstairs seating area feels like a quaint book store. It's a good place to come study/get work done or read. I loved their coffee and their espressos tend to keep up their end of the bargain. It's a dope local spot that is relatively quiet and accessible to the neighborhood. read more

Super cute location!! Fun phone booth in the cafe and good coffee! Love the pink lids on the to-go cups ;)

The place was small and uncomfortable. As my date and I walked in the door, we were greeted as if we had no right to be there or that they weren't expecting a customer. In their defense, they were planning for a comedy show. But if they were doing this to draw customers they, in turn, turned two off. I wouldn't go back, there are too many other places with better enviorments. Drinks were cheap though 4 something for a latte and expresso. read more

The place is adorable! It has little arm chairs, and it's cozy and homey. There's wi-fi and several little tables for your laptop. But, I have a few gripes - being Park Slope, the place gets a lot of kids, especially during the lunch hour. Also, their menu is really minimal. They have pastries, bagels, and soup. They also sell Cup Noodles (ick) I guess because of how many teenagers they get during lunch hour...I love to come here for the ambiance when the kids aren't here, but if I want a good luck, I'd definitely stop by 'Snice and then come back here because it's quieter! read more

Dig the off-the-main-drag and kinda secretive vibe to this place, which dishes out a great cup.

horrible customer service!!! No people skills at all. They need to hire an entire new staff that knows how to engage with customers and look them in the eye!! The coffee taste burnt and not worth any amount of money. I will NEVER return here read more

Love this place. I'm always extra happy when Aubrey makes my double espresso...I love to ogle him. The place itself reminds me of my old college rec room (which is why I feel 20 years younger when I walk in there). I'm in there once a week, I've met some great friends there. read more

Pros: reliable wifi and good outlet access, the music and chatting volume is not too loud, seating is usually available, and good natural light; overall a great place to get some work done. Cons: nothing special about the food and drink selection; closes too early! read more

Great coffee, great staff, great space. They even have events like story time for kids on Friday mornings and comedy night Friday evening. Love this coffee shop! read more

I do work at cafés. There are well sized tables to do work and many outlets. There is even additional seating downstairs. Wifi is fast. Americano is a bit weak. Staff seem friendly. They offered a free pizza bagel to the public because there was a mixed up order. I think the cafe is close to a school so there are many kids here at lunch hour which can get noisy. Music ranges from simon and garfunkel to top 40. Not my vibe but good place. read more

This is my new go-to spot. I love espresso and they make it just right. I get the galao, which is espresso and steamed milk, bigger than a macchiato but smaller then a latte. It is absolutely delicious and I need atleast one a day. Also they have some nice baked goods. Super cute and cozy too. Highly recommended. Cheers read more

My favorite quiet place to come and get work done. Really good coffee, and rather peaceful atmosphere. It's really like a hidden treasure found it on the exact day that was needed! Grateful for this spot! read more

This is my first yelp review ever, because this place deserves everything. I've been in mourning over the closing of Park Slope's Tea Lounge, but this does help. The pastries are amazing (the morning glory is an exploding croissant muffin with a teensy bit of sweet and cinnamon), they donate %100 of tips to a different charity each month, and show the total on a giant chalkboard when you walk in. This month they've chosen a disability group that works to enable and employ. The place is completely unpretentious while serving the fancy shmancy coffee and pastries Brooklynites crave. There's a kid's room and extra seating in the back, outlets everywhere for starving freelancers, and oh, they hide some coffee vouchers and clues around the place. What. Bottom line: Good coffee, good tea, good food, and a genuine friend of the community. Keep it here. read more

Loved this spot! Friendly staff, cozy yet productive atmosphere, and good edibles! If I lived in this area, I'm sure I would become a fixture at this place! read more

I just found out this place is a nonprofit! It's run by the Church of Park Slope and they are able to operate as a space for the community in addition to serving amazing local coffee and pastries. Service is always friendly and there are plenty of spaces to plug in your laptop if you want to work. Great park slope cafe without the pretense! read more

Charming little place! Dropped by for a quick breakfast fix. It's small but cozy, with homey art and decorations. The people are friendly. Ordered a cold brew and croissant, and they nicely heated it up upon request. Good coffee, and the croissant was so amazingly buttery and crispy. read more

coffee is delicious, atmosphere is great. and they now accept cards!! read more

Postmark is worth it just for the atmosphere. The upstairs is warm with nice vintage touches (like an old fashioned phone booth). Downstairs has kids games and books which is great for cold wet days. The chai lattes are delicious and the baked goods are from Coulsons and also wonderful. read more

Absolute best brew around town. I'll walk an extra 5-10 minutes out of my way to get a coffee here over any closer coffeehouse. Plus they have almond and soy milk as alternatives to milk. read more
