Absolutely gorgeous venue. This might sound weird but I think they have the most beautiful bathroom I've seen at a coffee store. Coffee is quite good but not my favorite tho. Not all espressos are perfectly poured so you don't always get the same quality. However this is me being super picky. Place is great. They also have a tasting bar for different beans.
I only had a decaf espresso here, but still have some thoughts. The coffee itself was bad (but again, decaf). The space is interesting conceptually, but overdone by trying too hard with the art and decor. Music was loud and annoying. The pastries didn't look particularly tempting either (and I was ready to be tempted). Lastly, the espresso cup didn't have a handle, which looked great, but was entirely impractical. Overall, I'd say 4B is overrated – there are far better places for coffee in the city.
