Ahah, I may check it out them waffles next time I'm in Belgium, if not just for the fun factor of taking a selfie at the station. Thanks for the tip
@OP You said Wednesday so are you going this week? Let us know how it pans out and what you found there! As an additional late tip, I would try and get yourself 20'000 cash before going. Yes they have a bank (with an honest exchange rate) at the airport, as well as ATMs all over, but you might as well save you those extra 5mns of time, which you will need.
Note that there is a 7-11 with an ATM just in front of Suehirocho subway station, so that's a convenient spot on your way. You will however need to get the subway ticket beforehand, and most subway stations do not take credit cards, so get yourself just a little change before travelling,
Enjoy!
