When I went to Tsutaya-Kaden, I found here. You can barely find restaurants which doesn’t have long line around Tsutaya-Kaden. This is the one which doesn’t have line, because I guess the place is located at 1st floor which is hard to find. I had a chicken(Hinai-Jidori, which is a speciality chicken in Japan) breast lunch combo. The restaurant were offering mainly chicken menu at lunch. You can refill rice freely.
