I am looking for a some advice regarding a 60th birthday dinner for my dad in the middle of May. I have been asked to pick a restaurant for approximately 6 people. My go to choice would be Scaramouche, but I have been told my dad wants to try something different. He generally likes relatively simple food. So far I am thinking of George, Jacobs and Co. (or another steak house, given his preferences), Chiado or Mistura (or another italian restaurant in a similar vein). What do people think of these choices? I am open to other and newer suggestions as well.
