I have eaten at kitchen tables at both Buca di Beppo (the now-closed Clark Street location) and Tru. Both experiences were several years ago.
The first was hot and cramped and with mediocre food (although I'd put it a rank above Olive Garden and much better than Macaroni Grill) but it was right in the kitchen and everyone working there made an effort to come by and talk to us and show us food as they took it out into the dining room. The folks who took me there enjoyed the food and had a great time. IIRC, we paid the same price for the food as on the regular menu and could order anything from the menu we wanted.
The food at Tru was stellar, as it always is, but the kitchen table is a separate, enclosed room within the kitchen. You can't really see any kitchen activity when you're seated at the table. We were required to get a 10-course degustation, which was priced at a premium over eating in the dining room. While Rick Tramonto was definitely on the premises when we were there -- we caught sight of him as we were led into the room -- no one except the waitstaff serving our food came in to talk to us while we were there and a telephone in the room rang constantly throughout our dinner. Eating in the dining room is way more fun.
Flight, in Glenview, has a kitchen counter; I have eaten at the restaurant, which is quite good, but not in that seating.
I understand that Stoney River Steaks also has such a counter, at least in their Deer Park location, where the chef does cooking demos on request as well as feeding you dinner, but I haven't eaten there.
Some of the Weber Grill restaurants have bars where you can watch the grilling, but I've always eaten in the dining rooms, so I can't talk about that experience, either.
