This is actually not one of the spots I visit often, but every once and a while when a friend is visiting from out of town I take them here. The view from the second floor café/brasserie is just breath taking.
The food is good, service is good but the view is the thing you should come for. From behind the big windows you have an excellent view over the river and the left bank of Antwerp.
There is also a big terras outside, but most of the time it’s quite windy, I prefer the inside.
