Me and my girlfriend came here every day once we found it!
We had breakfast here to start our day. If you're staying in the Q Factory hotel this is ideal and cheaper than their 'breakfast'.
We came here for breakfast but it's open until 11pm. The staff are brilliant. They give you water so you don't have to spend 4 euros on Orange juice or tea if you don't want to.
The pricing is reasonable. I would highly recommend the full cottage as it was the closest thing to a full English we found in Amsterdam.
