3. MandalayMandalay doesn't look like much from the outside - it looks like a 'greasy spoon' (English caff for a Full English Breakfast) – and it's only a small restaurant, but don't be put off as the food is fresh and tasty, as well as exceedingly well-priced. The menu is quite extensive but there's nothing complicated on there and staff can help you decide. Do call and make a reservation for dinner as most tables are busy for most of the night, although they do go out of their way to try and fit you in if there's a gap between bookings.
