While I have only been to J Cafe once, I will offer that it is not destination dining by any means IMO. It is clean, inexpensive, and tasty, but, not only do I think there are better Mid- Eastern restaurants in all of Chicagoland, there are better Mid -Eastern restaurants in Oak Park: Grape Leaves.
P.s. I'd pick Reza's over J Cafe in a heartbeat.
We cannot be friends if you do not know the difference between Mayo and Miracle Whip.
