A little taste of home for me. Kassab's also has the classic Lebanese restaurant decor that I definitely miss. I've only been once because I'm rarely in South Side, but I still dream about it...
I recommend ordering a mezze sampler, which has all of the classic Lebanese goodies (tabbouleh, falafel, hummus, etc) made to perfection. However, you must not leave without trying the sleek! Sleek is a lesser-known Lebanese dish that consists of stewed greens with black-eyed peas. It is lemony, wholesome, and all around amazing.
