I don't like the Flamingo, or many of Harrah's properties (now Caesar's) for that matter... I think they are seedy and have been allowed to run down.
HAVING SAID THAT...This buffet with it's menu, at the price, is really good. Yes they have all the breakfast goodies including bagels and lox, and some of the lunch items (we didn't go at the change over hour... we were there at 9:00am). There were shrimp and lots of other lunch time selections.
Caution... if you are driving, with the twists and turns, it is very difficult to get to the valet, and then it's a long walk to the buffet!
