Made a reservation for a Sunday afternoon tasting ...

Made a reservation for a Sunday afternoon tasting only to arrive to a locked gate - apparently van Ryn's is closed on a Sunday! This happened despite the online booking system allowing me to make a booking on Sunday, and receiving not one, but two notifications asking me to confirm my reservation for Sunday!! I spoke to a security guard at the premises and apparently there are a lot of people who had already been caught out by this. Fix your online booking system van Ryn's!!
