bar before it was

Shh... Sibin

Our doors opened in September 2022. Drawing inspiration from the ubiquitous Irish pub and the American speakeasy, An Sibin aims to be a reliable and comfortable gathering place to have a great drink, enjoy a bite to eat, and make a good friend.

Illicit Whiskey

We offer one of the largest whiskey lists in Cambridge and a craft cocktail menu that honors the history of generations past in bringing people together for a good time and a fine drink. With an emphasis on comfort and ease, our food menu offers everyone something they can enjoy. Our draught list is simple and supports local breweries.

Speak... Easy

Come in and have a seat at our intimate bar, people watch from the ‘nook’, or warm up by the fireplace. Welcome to your neighborhood hub, your second living room.
