We suggest that external participants have their breakfast at the hotel. Lunch is available at the MPI canteen. These meals, as well as dinners, will be reimbursed through a per-diem together with travel expenses, after the workshop.

Payment at the canteen is by means of a special card only.
In order to obtain and use the special card please follow these steps:
• There are 3 machines outside of the canteen in the central foyer. The leftmost one will provide you with the special card when you insert a bill. There is a deposit of 5 EUR for the card that you will get back when you return the card at the end of your stay. If you insert more than 5 EUR the additional amount will get charged to your card immediately.
• The middle machine is for recharging your card. It accepts bills and EC/Maestro debit cards. You can also check the current credit on your card in this machine.
• At your departure, please do not forget to return the card by putting it into the rightmost machine and choose the option to return the credit and the deposit. The machine will then dispense the money in coins.
