I have been here 3 times and I have to say that it is quite an experience. Check out the website for a brief history. They offer all-you-can-eat lobster tail and sushi. They are located in Woodfield Mall. Seats about 500. The food is excellent but the lines are pretty bad on the weekends.(1 hour just to get in not to mention the food lines) Weekdays highly recommended. I think everybody should try this place once. After my first time there, I thought I would never want to look at another piece of lobster again but....
I think it is a good place to go once every couple of months. The ambience is kind of lacking but that isn't the reason people go there. They clean plates off pretty regularly and the staff is pretty good. The sheer amount of food they offer is mind-boggling. Price is under $30 per so definitely worth a try. This might be a great place to have a FT gathering. They take reservations for more than 4 I think.
