Yes. There's a plate-splitting charge of $2 for the $4.99 chicken dinner -- half a rotisserie chicken, dinner salad, rice, beans, corn-on-the-cob, and tortillas -- at Terrible's coffee shop (served 24/7).
We don't recommend paying the $2 extra, which brings this meal to $6.99. Instead, if you're with someone else, spring for the second dinner ($9.98 for two) and take out the leftovers.
By the way, you almost certainly read about it in the Las Vegas Advisor Top Ten (the March 2004 issue). That's where we wrote about the plate-splitting charge for this best-chicken-dinner-in-Vegas deal.
