Union Coffee

This is a lovely cafe and the espresso is top notch. If you want real espresso in any of its manifestations, this is your place. The caveat is, apparently, to get your espresso before the start of the last hour of the day there. I recently stopped in around 4:00 on day where Union closes at 5:00. It was busy, but not overly so, and we got a nice table by the window. When I heard my drink called, I went up to the counter and was handed my cortado in a paper cup. Thinking this was a mistake, (everyone sitting around was drinking from ceramic cups, and there was a pile of fresh ceramic cups on top of the espresso machine) I offered that I had not ordered to go. I was told that "after four, we only use paper cups to spare the dishwasher." This is disappointing (and also odd), as the quality of the espresso is so good that it made the taste of the paper cup all that more present. As a friend put it, would a restaurant suddenly start serving on paper plates simply because it was the last hour they were open? One would bet not. Why people who order in the last hour are not permitted the same experience of the espresso, not afforded the same experience as people who paid for the same thing just minutes earlier, is not clear at all. It used to be that businesses were open, then did the clean up after closing. Very disappointing for such outstanding espresso. If you go, be sure to get there in time to not only order, but to receive, you espresso before the beginning of the closing hour. If I'd wanted my espresso in a paper cup, I would have ordered it to go.

What a welcoming coffee shop. The staff is very friendly, helpful and willing to make good suggestions if you want to try something new. The baked goods are delicious and the shop has some really unique items like this cocktail mixer and all natural bug repellent. I highly recommend stopping by if you are in the area.

Top top coffee and atmosphere with really friendly staff. Great little addition to Lambertville and I will be back many many times.

Edit: just to add, I’ve been back here dozens of times now and it’s easily the best coffee place in the area. Coffee is fantastic, baked goods are consistently good, and the atmosphere and service are just fantastic.

We visited on a Friday morning and it was mobbed. Coffee was very good and baked goods were great. Cute little shop, we'll be back.

Stopped by for a mid day pick me up. I love matcha because coffee hurts my tummy. I got an iced matcha latte with lavender and vanilla syrup. Would 111000% recommend!

We had really great coffee, hot coco, bagels, some pastries and avocado toast. Great location. Ample seating. Awesome staff. Will be back. Carolyn is the best.

Fine banana bread and excellent people watching in this small coffee shop. Coffee portions are a bit small and seating is limited. Highly recommended but also crowded. Never disappointed with the price or service.

Good location and pleasant décor as well as staff. This was my second time there. My wife enjoyed a mocha and my daughter liked her chai latte as well (although the latter came from a box). However, I found the expresso lacking. The barista technique was competent so I have to chalk it up to whatever roasted bean they used. It was more bitter than an authentic espresso, even a dark roast. So, I'd recommend for coffee, or a mixed beverage but not a good option for a straight expresso.

Really fun vibes and great service, but the drinks were okay, not great. Chai latte was good but didnt really taste like chai more like cinnamon. Really fun space though.

Lots of vegan options, also might be the best espresso I’ve had in a latte in a really long time. I love this cafe.
