First off, I am not a fan of buffets. I don't visit them. So I have very little to compare to.
I took my work crew here because its 1) close and 2) cheap. At $9 per person they can get their grub on (which they did) and enjoy a nice variety of foods from Chinese to Mexican to American to Italian. None of it is high quality. The pork loin was good, but you won't order that at Michael Mina's and be impressed. Even with the turkey gravy on it.
What I did enjoy was the service. From the front cashier to our table waitress, everyone was super nice and did a great job. Even the grumpy carving guy, after being asked "no turkey" for the 20th time could manage a smile and laugh at my follow up joke "No turkey for you" .
I do this crew buffet meal once a year, to show my appreciation for all their hard work. Normally I BBQ ribs, chicken, steak, carne asada, stuffed burgers and other meals throughout the year. The one advantage to going to the Fiesta is after lunch I can treat them to a shot and a beer, which I'm not allowed to do on property (thanks stupid lawyers).
