What customers say

A sweet little spot in Mount Vernon, a minute from I-44 with outstanding coffee in a welcoming atmosphere. Plenty of parking, indoor and outdoor seating, and a drive-through. Very kind, helpful, friendly staff who offer recommendations from their menu with a wide variety of drinks and food items (see menu pics).

Fantastic Coffee. I had my usual iced mocha. Keen Bean’s mocha was excellent. Prominent coffee flavor at the beginning of the drink that was not overwhelmed by the chocolate or over diluted by the milk. The flavor lasted until the last sip. My expectation for a perfect Iced Mocha.

Very fun atmosphere! The decor and outdoor seating are an added bonus. Everyone was very friendly and the coffee was great!! Awesome selection of whole beans and other products. Good parking and a drive through.

I have such childhood nostalgia around KeenBean as I went often with my family then. Recently I went back for the first time in years and it still impressed just as much as I remember from years ago. KeenBean still holds the prize for the best coffee in my heart. Also their atmosphere is such a vibe.
