Station properties "All You Can Eat Tacos"

I see that most of the Station properties (Texas Station, Palace Station, Aliante, etc.) have an "All You Can Eat Tacos for $8" deal at their Mexican restaurant/bars (mostly Cabo, but a couple of other names slip in). Is anybody familiar with this, and if so, should I be expecting something more than the equivalent of buying $8 worth of tacos at Del Taco?

(And let's keep the "forget both of those, and go to Tacos El Gordo instead" replies to a minimum.)
