We use to eat here regularly, but its always only OK. It use to be our Sunday after church spot, but we haven't gone in a while. It is one of the better Station buffets compared to the Fiesta Rancho (absolutely terrible).
The line tends to vary depending on the time of day. It gets packed starting in the afternoon. The good part is that you can get discounts for taking surveys and having a players card. If you like fast food, you won't be disappointed. Its only slightly better than the drive thru.
