We were rather disappointed after all the good reviews for Lille and the Grande Place but then our benchmark Bruges is very difficult to live up to. Like much of Lille it reflects the state of the economy and there are many vagrants (man and a can) about, which although are not a problem can make you feel uncomfortable.
Again like most of Lille English is not widely spoken and signage in English almost invisible so if your French is poor like ours you will have no idea what the restaurants are offering. We even had problems ordering in MacDonalds which could have been the staff having a laugh at our expense. How can they not understand McNuggets when there is a big display on the wall you're pointing to?
Yes we had a good weekend but would we go back- No, it's Bruges again for us for so many reasons.
