Fado Rock will do takeaways if you ask them.If you ask a lot of the restaurants are quite happy to do a take away for you.I have seen lots of people over the years coming out of various restaurants with little bags or items in tin foil
As janpaul said just about everywhere do takeaways. A favourite of ours to have on the patio is a rottiserie chicken, nice crusty baguette (or bocadillo) salad and some gorgeous saute paotatoes (cooked with garlic, herbs & onions) that you buy along with the chicken Tha Cave (opp Fado Rock) do great pizzas too.
