"Having just returned from a trip to Paris, I was craving pastries similar to what I enjoyed there and decided to finally try Un je ne sais Quoi… after hearing so many great things. Unfortunately, my experience didn’t fully match the hype, though I’ll admit my expectations may have been influenced by my recent travels. I ordered a canneles, a pain au chocolat, and a pear tart. The pear tart was excellent, no complaints at all. The pain au chocolat, however, left a bit to be desired, as it wasn’t as flaky as I would expect and lacked a few pieces of chocolate. The biggest disappointment was the canneles. It didn’t seem fresh and had hardened to the point of being nearly inedible. It also lacked the signature custardy interior and the classic rum and vanilla flavor that define a good canneles. Before leaving this review, I called the shop and spoke with a manager to share my feedback. They were incredibly receptive, transparent about the challenges of running a small business, and clearly committed to producing high-quality pastries, even acknowledging that sometimes things may miss the mark. That conversation really stood out and showed they genuinely care about their customers. Because of that experience, I’m more than willing to give them another try in the future. While this visit wasn’t perfect, the customer service and willingness to listen to my feedback made a strong impression. Sometimes customer service matters more than anything and they proved that today."

"This bakery mainly focuses on hot baked goods and bread. There are around 6–10 chilled desserts, but the selection is still fairly limited compared to the bread options. The shop is small, with about 20 seats and 5 small tables, plus one long communal table by the window. The French-style bread is decent, good flavor and quality but not particularly memorable. The coffee is average — drinkable, but not especially good or well-crafted. Overall, it’s a convenient spot to stop by for bread or a short break, rather than a place for high-quality coffee or a wide variety of desserts. Ì you just have one day in W I think you should try Tatte where more plenty choice, nice place really near Un…"

"This pastries was EXCELLENT It's my favorite place. Coffee and amazing pastries I love chocolate tarts, canneles croissant above all for the exceptional service. I have to go every time when I go to DC. There's always a long line, so I choose to go in the morning."

"Un Je Ne Sais Quo the kind of bakery that wins you over before you even take your first bite. Tucked into a very small, quaint space, it feels like a hidden gem—intimate, warm, and full of character. The staff is wonderfully efficient and genuinely helpful, creating a smooth, welcoming experience even when the shop is busy. Their attentiveness adds to the charm, making the visit feel personal rather than transactional. What truly sets this bakery apart is its impressive selection of French pastries. The offerings are abundant, beautifully crafted, and widely regarded as some of the very best in the city. Whether you’re craving something classic or looking to try a new indulgence, the quality is unmistakable. A delightful stop for anyone who appreciates authentic French baking—small in size, but overflowing with excellence."

"Unfortunately, the service was disappointing — one staff member who is a white female. She was unfriendly with eyes rolling when we ask for forks/knives. Visited 9/7/2025 Sunday 2:40 PM. Feel like I owe her $1 million. Pastries are good that I can give 5/5 if ignoring the negative services (please just let us do self-service order on machine, that will save your business money too) Recommend the pistachio Paris Brest which isn’t overly sweet and works well for Asian tastes. The lemon tart was quite sharp but I like it."
