For people who are new to these dining rewards, you get 3 miles per dollar until you have 11 "dines" (transactions) in a calendar year, and then starting with your 12th, you are "VIP" and you get 5.
For the drinkers out there, a nice trick to fast-track to VIP is to sit at the bar and not run a tab. Close out after every drink; every charge is a separate "dine".
