All American Dave (Dave Swanson) is a pretty good trainer and a fairly decent cook.
The food he makes is very good and cooked without oil (usually any meal you get has tons of oils which is fattening and not good for you).
Is it over-priced? You betcha. What isn't at the Rio?

It's better than the Poker Kitchen or running over the Burger King "Burger Bar".

I think Dave pays a lot of money to the Rio in order to operate his food truck there.

You can save a little bit of cash by using a "meal plan".
Yes, the girls he uses to run out the meals are trying to hustle you out of $5.

Instead of trying to place an order on Twitter and over-tipping a girl who isn't giving you a table dance, you could just walk over to his food truck, place an order, pick up the food yourself and not tip anybody.

If you think Dave is over-charging, Cyndy Violette and Annie Lepage are charging far more for their vegan meals.
