If we arrive between 1:00 and 5:00 pm we get two points for each $ spend so spending $50 gets a $10 payback. Also $2 off gold 55 menu items and free soft drinks. If we arrive outside of that time window, it is the standard payback deal.

Of course we go because the food is very good; the paybacks are a big plus. While we go down stairs to CJ on occasion, we normally opt for TB on the upper level.
