Students of any age are eligible to apply for tickets for the university restaurants under the direction of CROUS de Paris. A list of addresses, which includes numerous cafeterias and brasseries, is available from their offices at 39 av Georges-Bernanos, 5e (tel 01.40.51.36.00; Mon-Fri 9am-5pm; RER Port-Royal). The tickets, however, have to be obtained from the particular restaurant of your choice (opening hours generally 11.30am-2pm & 6-8pm). Not all serve both midday and evening meals, and times change with each term. Though the food is less than wonderful, it's certainly filling, and you can't complain for the price . Some are less fussy than others about student credentials, and will sell tickets to anyone for ?4.30. They will cost you ?2.09 if you're studying at a French university, ?3.51 if you can produce an International Student Card.
