    Really high quality hot chocolate and the store sells some nice and healthy groceries. Definitely a bit pricey but you can find good products here. The chocolate croissant looks better than it tastes.

    My friends and I stopped by Mast Market to grab a cup of coffee before our trip to the the Museum of Natural History. The market is spacious and welcoming. It was fun to peruse the shelves of grocery items while waiting for our drinks. There are plenty of snacks, beverages, and household items like soaps or cookbooks. The coffee was good and the space was a nice refuge from the cold weather :)

    A modern coffee shop with a rather interesting layout. The "store" (to buy items) is at the front entrance, while the open-spaced bar to order coffee is placed closer to the rear. Prices are fair and the coffee is good, albeit unspectacular. My one gripe is that while there's an abundance of space, there isn't too many places to sit (1-2 tables, and one window bar area with 4-5 stools).

    Vibe: 3/10 - I know what they're going for, but it didn't feel clean. Service: 2/10 - friendly, but the coffee is self serve so expectations are low here Value: 2/10 - I came here after seeing the coffee was only $2.50, but this was the smallest non-espresso coffee I've ever seen. Coffee: 1/10 - completely self service from a coffee urn and the cashier handed me a carton of oat milk to serve myself as well. The coffee was cold, watery, and acidic. Not even worth the $2.50 Overall: 2/10 (1/5) [To clarify our review system: 10 = we'll never have anything else as good as this in our lives (we use 10 very sparingly!) 9 = extraordinary 8 = great 7 = above average 6 = average Anything below 6 is being critical]

    I am 71 year old Upper West Sider. I Live around the corner from this place. This is your basic new, stark retail coffee/grocery store staffed by typical "high on life" rural GenZ's who lack any trans generational engagement or connection. A Rikers Island visiting room has more welcoming ambiance than this place. I was on my way home, in the oppressive 94 degree heat when I decided to go to Mast for an iced Chai tea. Before ordering I was told that they couldn't process credit cards, only cash, due to their system being down. The cashier added that I could sit and wait for the system to reset. I asked if I could get my chai because I was hot. He hesitated and agreed. I also explained that I'm a longtime neighbor which really didn't mean anything to him. He didn't engage. Like a wall. I sat down and finished my chai beverage . I got up and headed back to the counter where I told the guy that I was going to an ATM to pay for the chai. At this point let me note that the Upper West side businesses have usually been accommodating and kind to their neighbors when in crisis. Unfortunately, these new generation Utopians are virtueless, and lacking any common sense or discretionary outreach. In their eyes, they are the pillars of social morés because they sell farm food when, in fact, they don't assimilate to our community! Their system was down and it never occurred to any of these wizards to use discretionary thinking and accommodate me, the customer! You remember what a customer is, don't you? Apparently not! Is a $5.44 beverage worth making a disabled senior walk FOUR blocks in oppressive heat? Apparently, $5.44 is their priority! So much for empathy, and community! Real New Yorkers would use discretionary thinking and either comp me the chai (after all, it WAS their system that was broken!) or simply say " don't worry about it. You can pay it the next time you're here" But that would be kind and caring. Both virtues that these farmer zombies lack! So in 94 degree weather, I had to stagger 4 city blocks to an ATM to get the $5.44 for the priceless Chai! This is New York now, friends! We have foreign immigrants and domestic ones. The domestic ones are just as alienated to New Yorkers, and communities, as the foreign ones. When I returned to the store, I paid the $5.44 for the precious Chai! The women behind the counter ignored me. No surprise. Their arrogance was as glowing as the sun outside! This place is the farthest away from "community" than you can imagine! More like "farm girls on parade with New York attitudes!". Morgue freezers have more warmth by far! Ever wonder where the Children of the Corn wound up as adults? ....I know.

    Mast Market is my wife's favorite coffee shop in the city. It's bright, clean, and has very good coffee. The baristas are helpful and supremely patient (I witnessed another customer express profound confusion when her four individually-modified matcha lattes took longer to prepare than my black drip coffee. God bless the baristas for their calm, repeated explanations as to why). The curated decor is cool. It feels a bit like stepping into a influencer's TikTok. But you can actually hang out, sip your flat white, and just vibe. Or peruse the kitchen cookware and buy something to make your own home feel just a little bit cooler. Also, I really appreciate the farm fresh produce for sale. When I visited (October 2022), Mast offered local honeycrisp apples. Fellow apple elitists, rejoice.

    I love Mast Market and go almost daily. Their organic produce and even books are fantastic, their coffee, lattes and staff is friendly. My favorite staff member however, barista Jamie McDonald, is not there anymore. He brought so much to the place: warmth, great customer care and the BEST LATTES . I have heard from other customers who are regulars as well, how much they miss Jamie! Please bring Jamie back! He makes the difference, if my friends and I frequent Mast.

    Decent coffee and friendly staff. I ordered a small cold brew ($4 + tax) which was decent. Complimentary almond milk yay! Apparently, the pastries are made fresh at Mount Kisco and delivered daily. Definitely will come back to try the pastries and possibly a gourmet soup (saw that they used grass fed butter).

    Best matcha ever!! Me and my friend can't stop talking about it. It tasted fresh and not too sweet. Had a very nice after taste

    Solid coffee shop on the UWS. I enjoyed the iced chai latte! Service was friendly and there's some tables inside the cafe as well.

    Pretentious and overpriced!! One avocado to go sells for $4.50. A lot of other items you can find on Amazon for a fraction of the price

I was looking for my friend and was able to reach him via cellphone, I told him to go into the closest store for help which happened to be health food & vitamin city. I asked my friend to hand over the phone to the only employee there so I could get a bearing on his location, I was coming from Glendale Queens NY to try and get him. I tried to explain to the employee that my friend suffers from mental issues, to please keep him there while I arrived. When I got to the store about 15 minutes later, my friend was gone.

This used to be sweet bistro where many days and nights were shared with friends. This particular storefront is even more rare because it's not a chain and is open late, for the way working folk have needed to live here for a long time. It's not Whole Foods or Vitamin Shoppe (or whatever that chain's named), but a humble spot where the selection of vitamins, herbs, topicals and a few pantry staples probably contains exactly what you're looking for. Ask any of my neighbors what they think about your cough, sniffle or dry skin, and they'll tell you, "Go see the vitamin guy on 23rd." And you should. Because for years, he's dispensed sound counsel to a number of us whose needs aren't easily addressed by either of those aforementioned chains or that chain pharmacy who makes you summon a worker to unlock some dental floss. I'd been recovering from RSV when my husband stopped by the Vitamin Guy and told him about my lingering cough and shallow breathing. He brought home some Olbas syrup and a tincture containing a melange of herbs, half of which I was familiar as a TCM patient for a number of years. Within week one I was feeling great relief. A neighbor who'd been hit with the same condition went and had his own chat and relief success story a week after me, and unprompted, said, "Vitamin Guy saved me again!" This is but one of many ways Vitamin Guy's helped me, my husband and many neighbors over 18 years. Go see him the next time you're wondering what you can do about whatever's ailing you; he probably has some sound advice to share, and you'd be keeping the lights on amid the many otherwise darkened storefronts that don't exactly inspire confidence around greater Chelsea.
