Always use this and couldn't find it on here so thought I would post. Tis my first too so sorry if I get something wrong.
This is on student beans and although the T&Cs do not state that a student card is required, I can assure you that one is as they take your name and card/student number (not sure why - probably to claim from head office or something). I have been with a group of 4 and I think only one was required but it might have been 2 so a good rule is 1 card per 2 people at least. They have changed it from maximum of 4 people to 8 so I imagine they would want a student card each in that scenario! But this could be different with each restaurant so try and be honest and make sure everyone has student I.D! ;)
A great deal and you could use the student beans Cineworld deal (Mon-Thurs) for a very cheap night!
I would recommend the Calamari or Polpettini to start followed by Penne Ricce Marco Polo!
