For our trip in October, we have a few set reservations for each of the cities we will be staying in: London, Edinburgh and Dublin. Other than making one more reservation for a restaurant in Edinburgh, this gives us a few free nights in each city to leave to chance. I like popping into a restaurant that catches my eye while roaming about during the day and making a reservation for that night. Is this feasible in the 3cities we'll be visiting (I can guess London might pose a problem)? We do this often in Italy. Of course, in Italy it is mostly local trattorias that we do this with, that being the idea of a trattoria; no formal reservations 2 weeks in advance, etc., just a few hours notice for later that night and you're in.
Thanks for any input.
