I think there is a Rodizio grill around there. Not sure on price but the food was varied and good.

ETA: Apparently I am out of the loop. It isn't there anymore. The Fort may be a bit over what you want to spend, but well worth it. $35 each or total?

ETA 2: again lol. I have gone full retard. There is a great mongolian BBQ off Arapahoe and Quebec. A bit east of where you are looking but All you can eat and very good.
