Sundays are packed as the local community has started coming in. I found the portions to be pretty good myself (especially for the three sides); but in a buffet town I could see where some people may find them small.
You can get many of the dishes fried or grilled (I've had the catfish fried and the red snapper grilled -- both good.) I have to agree with Mrs. P though, the liver and onions (with gravy of course) were really good.
Great find in North Las Vegas! Highly recommended.
