We have tried the breakfast and dinner buffet and neither one is really special. They aren't horrible, but they are definitely not worth any extra effort to try. If you are staying at TI, the buy one get one free is a good deal, but I wouldn't even cross a street to get to these buffets if I didn't have to.
Overall, if we are staying at TI and are too lazy to leave, we will most likely visit this place again.
