I was on business in Antwerp, I live in New Zealand. I went into The BBQ on wet Monday night about 6.30 in September. There were no customers at all in the restaurant, I asked for a table and was told by the member of staff at the front desk that, and I quote, "we only accept Belgian credit cards". "Oh really" I said, "yes unless you have a Belgian credit card you cannot dine here".
So I left, how strange this restaurant apparently only lets Belgian residence dine in their restaurant. Seems like an odd business model.
