What customers say

I recently stumbled upon a charming coffee shop nestled in the heart of Hightstown downtown. I decided to indulge in their medium iced Maple Latte, and let me tell you, it's a game-changer! The espresso is the perfect blend of robust and smooth, powering me through the entire day.

Fantastic place. I found the liquid gold and I cannot "espresso" how much I Iove their coffee. You can also buy coffee for home. The coffee beans are slightly expensive but 100% worth it. I don't think you can find higher quality and freshly roasted coffee beans anywhere in this area.

Little Key Coffee has changed my perspective of coffee for the better. Their roasts are absolutely delicious and we make it a point to keep their beans in stock in our kitchen. The staff are friendly and knowledgeable.

★★★★★ — Sam, 2021-01

10/10. I’ve been stopping in every couple days for my morning coffee, as they’re conveniently located in downtown just minutes from me. Their espresso is BOMB as is their drip coffee. I’m so happy a good coffee shop opened in town.
