Some will sell you at the cage. Easy enough to get from the tables. Jetons are normally on Bacarrat only and may only be open late at night. Plaques are normally given when you draw cash with a credit card at the cage but some have them at the tables to cash up to before you leave (but that way you have to pay!)

Chips are expensive in Monte Carlo Most places lowest value you see out now is €10 ($13)
