I have to say, after six months in Qatar, that this is by far our favourite place to eat. We were suffering a little homesickness a while ago and went to L'wzaar for British Fish n Chips. The food was great, but the whole experience was simply outstanding.
On our first visit, the restaurant was fully booked but the staff pulled out all the stops to get a table for my family of six within half an hour. That can't have been easy!
