I have been to Betty Boops on two separate trips to Amsterdam, one in March 2013 and the other in August 2013. Out of all the coffeeshops I have visited in Amsterdam I have found Betty Boops to be the most comfortable, with a great quiet atmosphere, nice music and friendly staff. Every time I have visited Betty Boops I have spent a great deal of time there and been very happy. The staff are friendly and their products are good. Actually good coffee too!
