In case you have some free time and curiosity, I can heartily recommend visiting Wynand Fockink, a proeflokaal or “tasting tavern”. They have been distilling their own genever – Dutch gin – and liqueurs since the seventeenth century, and they have a huge selection. You can try anything, for (what I recall to be) a very reasonable price, either at the counter or as part of an organized tour including the distillery itself. They seem to be open 3pm to 9pm, at Pijlsteeg 31 in the city centre (20 minutes walk from the venue). But it’s tiny, so don’t go as a large group.
