I waited for 10 mins to order. It seemed like no one worked there. Then when the dude finally showed up he wasn't apologetic at all and seemed like he really didn't want to be there. Also the worst cold brew i've ever had- hands down. read more

I try to avoid yelp reviews but sadly this has to be my first one. I'm a regular that stopped coming after a while and my return wasn't a great experience. I ordered an iced latte and had gone to the bathroom. When I came back the young new guy hands me an ICED ESPRESSO, tells me to add the milk at the condiment bar and still charges me 4.50. When I added the milk it tasted disgusting so I asked for a price change and he told me he didn't know the difference so I had to look up at the menu and do the calculations for him. He'll probably tell his manager that he didn't add the milk because I didn't specify but any REAL barista knows that usually if it's not specified it means whole!!!! & if it was that big of a deal he could've started it when I returned to the counter. I do miss the the girl with the shaved side though. She would've never treated any customer like that. read more

This place is really chill for several reasons: the folks who work here are incredibly kind and genuinely attentive. I always appreciate a place with good vibes. Second, they have cold mate, yerba mate, and cbd infused drinks, which is really awesome for folks like me looking for some energy but not into coffee so much. TCU has plenty of table space and wifi, and a gender-neutral bathroom (yay!) and is open a bit later than some cafes in the area. I'll be coming back again to get some work done for sure! read more

i've come here almost once a week for the past two years because i live right down the block and the iced oatmilk latte is always on point! i also love ian. however, i finally felt compelled to leave a review after the recent new hires who seem to be high school aged children. they are quite awkward, either very loud or very quiet, don't seem to have any barista experience (understandable due to age) and some of them are even rude. makes the experience a lot less enjoyable :/ read more

Caffeine Undergrind is such a cool vibe , and they always have cool people coming in, sometimes even soothing djs! read more

The customer service was above average. The coffee wasn't the greatest. The cream may have been near end of life. Tasted a little pungent. I will go back and try something else. I liked the ambience. read more

Good coffee and bagels. Also there wifi is solid since I was able to get some work done with no hiccups. One of those cool local spots.

Great place! Always a friendly face behind the counter, whether it's the owner themselves or an employee. I take my dog there in the morning and he is always excited to get a treat. The coffee is also pretty darn good, and there is always a feeling of community. Plenty of fun events posted around that I haven't been to yet, but plan to. Also the food is yummy, and very fairly priced. Halleluja! Glad I found it. read more

Diehard fan of this spot. One of the hardest working men I know is doing his thing day in and day out to make sure that we are getting what we need out here in the city. A true warrior helping us get caffeinated one drink at a time. read more

This place is awesome. Went for the first time today and had a great iced latte. The owner is really friendly and welcoming as are the customers. This will be my new hangout! read more

Rated best coffee in Bushwick by Bushwick daily. I have to admit I have a little bias because the owner is a neighbor, but even this is good- a shop owner who is also a resident. Nice and relaxed setting with a definite New Bushwick Vibe to it. read more

Ian and his staff run an incredible, warm, homey, comfortable environment. But honestly the reason it deserves 5 stars is more about the amazing coffee. For $2.25, it's gotta be my favorite coffee in NYC. Especially when the owner Ian is there, he's obsessed with making sure my cup is heated and that the coffee is fresh. (Ian, make sure you take care of yourself and get enough sleep. You 100% deserve it!) read more

Just the coolest. I feel so at home there and the coffee is pretty good. Might seem simple but their toasted bagel with cream cheese was perfect. read more

The CBD coffee was really good. If you're looking for an immediate affect (spell check effect?) it won't happen. However it was still a good cup of Joe and the dude working there was really chill. read more

Just your typical hipster coffee shop, nothing fancy. The owner- or who I assume to be the owner- was very welcoming and down to earth. I came here specifically for a CBD infused latte which I enjoyed. His dog was also very friendly so that made my visit that much better. read more

Chill vibes. Friendly baristas. Quiet place to still outdoors in the shade. Pet friendly. Good iced chai tea. will be back

Chill vibes, great coffee And the baristas are so Kind and helpful too! read more

I love this place. It's so relaxing and not at all pretentious. The customer service is great and there is always a friendly face. Oh yes, and the grilled cheese is sooooooo good. I'm hooked. read more

so happy that this place is a block away from my apartment! greta coffee, always some cool music playing. overall great vibe. the owner is sweet and seems like a down to earth guy who just wants to bring the neighborhood and community together i mean, i walked in one morning and there was a woman in the front playing the violin? lol amazing tarot card readings at night sometimes read more

We love this place!! Great menu. Great service. Great atmosphere. All the classics plus Yerba Maté & Kava tea, Cannabidiol infused Flower Power coffee & edibles, pastries and more. Café owner Ian is super nice, and he makes a great cappuccino. Original artwork all over the place, likeminded people, and lots of cute dogs stopping by! This is our favorite coffee shop ever. read more

Been meaning to pass by here for a while. Finally had the chance to grab a cup of coffee. It was a good cup,nice service right when I walked thru the door. Almond milk available . Very artistic layout with several pieces of art for sale on the walls. I wasn't to crazy about there lighting and slight over kill of art but this is just my preference. Place was nice,lots of seating and staff was nice as well,and have a bathroom available for customers. read more

My coffee was excellent and the barista was very helpful. He answered all my questions and made terrific recommendations. Plus, they had kava on the menu which I'm eager to try. They also have Wi-Fi, outlets, and ample seating. I was able to sit for a few hours and get a lot of work done. I will be back! read more

Rundown, grungy-looking (and not sure if that's an intentional part of the aesthetic) but incredibly friendly place in Bushwick! This place just hits the spot on a Saturday morning. You can linger for hours, and bring your laptop to get a bunch of work done. read more

The place has a cool vibe. The coffee is good and the food is good. The owner is a cool funny guy, however whenever he is stressed he often takes it out on customers which is totally unacceptable. I don't go there anymore because I don't want to deal with his mood swings when ordering coffee. read more

Lovely staff, good coffee, cute resident dog. Printing available, too!

Great place. Love that they serve variety coffee and have a bunch of different drink offers. Sell every cod product under the sun as well. Love the little dog that hangs out inside. read more

This is my favorite coffee shop in Bushwick! Love the house drip, love the bagels, love the vegan options, the staff is great, plus, there's plenty of space to sit down with your book or computer, and kind customers. read more

I love this place. The coffee is amazing, the owner super cool. He took the time to teach me how to make a bulletproof coffee at home. Oh, and the art in the place is dope. Love love love! read more

Good coffee and quirky artwork on the walls! If you're looking for a change of pace from Starbucks, this is the place for you.

One of the best spots in town. Great vibe. Great people. Serves almost as a community hub for local artists.

Read an article and saw an online video about this place and the different types of drinks they offer. Since I was doing my last placement in the area, I thought I would treat myself after work. All of the people who took my order were beyond helpful when suggesting items. I enjoyed this fruity tea that I can't remember the name of and their coffee the most out of all my visits. I wish there was another location closer to where I live so that I could visit more and enjoy their beverages daily! read more

This is my favorite coffee shop in Bushwick- the coffee is really good, the owner is super nice, and the vibe is ACTUALLY chill and welcoming. The CBD coffee is nice and not too expensive and the baked goods are always great (I usually get a brownie). It helps that it's like 2 blocks from my house, too. I definitely recommend if you want a good cafe and good coffee. read more

Omg omg omg they have bulletproof coffee with charcoal! This is the first place other than Whole Foods I've seen with it. And they made it goooooodddd!!! And they have cool books to read and play cool music. And they have stevia!! I know stevia isn't a big deal but most coffee shops dont have it. Come here! read more

Pretty cool spot! Nice staff, tons of room, good menu. Could do without that weird old guy who is always in there annoying the baristas and complaining about the way poor people dress when they walk down the block though. read more

Just went here for the first time tonight with a friend, definitely will be coming back! Loved the ambience and the barista was super nice. I got a cheese danish and a CBD infused cup of coffee, which were both delicious. The set up is super cool and different, not your typical cafe, which makes it stand out even more. There was also some live music, which I thought was super relaxing while drinking a cup of coffee. My friend had the CBD infused latte, which she also said was great. If you're ever in Brooklyn, definitely check this place out! read more

Great coffee, great food, and really chill vibes! It's one of my favorites and I stop by whenever I have the chance to

Love the coffee, love the pastries and muffins, love the owner guy! My only complaint is that if you list your hours as 630 am on a week day... please be open. Home girl has to go to work, and I planned my morning around making sure I had time to come by to grab a coffee. Had to resort to bodega coffee. read more

As soon I heard this place was open, I had to go in and try it! They have a great menu and an even better atmosphere. It's a really big, welcoming space that feels like the sort of place you'd want to hang out with your friends. I had a delicious matcha latte that was really nicely made and not too sweet like so many places tend to do. I'll definitely be back! read more

Art events, nice bright and large space, a super sweet barista (didn't get his name) he's the bomb!! Variety coffee is served. Good looking pastries too. Between Wilson and central ave on Putnam. read more

Stayed warm here working on a drawing while sitting on a comfy couch drinking great coffee and eating a delicious bagel. Sat around for a few hours. Overheard some great conversations. Would highly recommend. The person who runs the place is really nice and friendly too! read more
