Great little coffee roastery that sells a large selection of coffee beans for both filter and espresso, light, medium and dark roast. We buy most of our coffee beans here, and the selection is large enough and changes frequently enough for us to not get bored. All the coffees are labelled with origin and tasting notes which is really handy. Prices of beans are average for specialty coffee, but depends on the exact variety. They sell large 1kg house blend bags for espresso if that's convenient for you. They also sell a variety of brewing equipment, but nothing too crazy - don't expect to buy an espresso machine here. Think aeropress, V60, filter papers, cups and hand grinders.
The store is also a small cafe too. You can get espresso (and cappuccino, latte etc) or filter coffee to sit in or to go. They also sell a selection of homemade cakes and pastries. The only downside is that the cafe is quite small. Often you'll struggle to get a seat if you want to sit in. On the plus side the canal or even the park is not too far.
Staff are friendly and happy to give recommendations on coffee (though on weekend mornings it can get very busy!). Payment is with credit card.
