Is it bad Yelp protocol to review a restaurant you haven't actually eaten at? Wait, because I've got a pretty good excuse. Big Jack's shares premises with Souvlaki Express, where I was recently inhaling a gyro. While I was there I observed two men - large, sturdy, hockey-sweater-wearing men who looked like they knew their way around a burger - devouring and raving about Big Jack's Opa burger to anyone who would listen. The words "Wow", "incredible" and "off the charts" were used multiple times. Now I'm very much looking forward to giving it a try. I felt that this ringing endorsement should be shared!
