Many branches across Thailand. We visited Siam Paragon branch. Since it was near lunch time, the place was very crowded. After waiting 10minutes, we were seated and ordered "bento". Rice is unlimited, so you can eat as much as you can if you want. The quality of food was quite nice, considering the price. I am happy to go there again. They also deliver food, so dont forget to pick up the brochure in the restaurant when you leave. If you get hungry at hotel, you can order them.
