Important note if you want to have lunch at the mensa:
All meals at the ENC mensa have to be pre-ordered by 8:30 of the corresponding day. For this, visit the pre-ordering webpage. Unfortunately, the form is only available in German for now. Choose "Mensa ENC" as "Einrichtung" on there, then the day you want to pre-order for and the dishes you would like. There is always a vegetarian option, one containing meat and stew to choose from. Also, do not forget about side-dishes and dessert! Once chosen, confirm your order with pressing "weiter" on the bottom of the page and then entering your name and email address. Confirm this once again with "weiter". You then get a summary of your order, which you can also confirm to complete it.
You should then receive an email to the address you entered in the form. This email contains a QR code, with which the food can then be picked up (between 11:30 and 14:00). You pay for the food at pickup; this is only possible via card!
