The Beni is a famous all over Antwerpen. Actually the place ain't that shitty, almost every guidebook writes about it. It's still the best in town! Although they have some serious competition these days with Falafeltov at the hoogstraat. Only they lack the atmosphere and decoration... In this joint you'll find all range of people from the hipster regular to the big Indian Family. You'll never feel alone in this place.
If you're into humus def. try the Falafel Humus or the Falafel Schotel.
A small note: they are closed on Saturdays because of Shabbat. It wouldn't be the first time standing in front of a closed door.
Lange Leemstraat 188
