Went to Brindley Place, Birmingham today and noticed this deal advertised outside a nearby Slug & Lettuce.
Thought it was worth a mention ;)
I'm there the next Monday I have off. It said all day as well so I don't think this is a time restricted offer. No vouchers required!!
Ooh and almost forgot to mention, if you sign up to their newsletter on the website you should get a £5 off a £10 order voucher.
