Although not in Antwerp, Amsterdam or Paris food is not bad at all.
Portions however, are not European but goliath. I mean huge portions!
Lot’s of burgers, oversized pizza’s and buckets of pop drinks.
Katz’s is one of those places you should visit for the atmosphere, they have a wall of fame and BIG sandwiches. Believe me, one is enough for 2 stomachs. Don’t forget to go to Sylvia’s as well.

But no panic, you can find healthy food as well.
Same for a good cup of coffee & biscuit.
In central Park there’s even a ‘Pain Quotidien’ Yezzz, Belgian food.
