We had booked a table for the late "shift" (20.30) through their website, and they barely had a table available when we got there. The place was absolutely packed with people, so it is very popular and reservations are in order.
They found us a spare table real soon, and we were provided with a drink and a snack fairly quickly. Although a busy place, we weren't disturbed by the background noises, though some people may be. The food was great; you get the occasion to discover new exotic ingredients, and they are all presented in a delicious way, with an explanation by the waiter. For wine lovers, there is a big wine list or the sommelier's selection to go with each dish, in different price ranges and with clear indication of tastes.
A must for people who visit Haarlem. But make sure you book in advance!
