I would recomment Palmerston or Franklins; the latter being a little more pricey, and challening (i.e. lots of offal and game). Le Chardon is too hit-and-miss for taking the parents or in-laws. If you go for the Palmerston, you will need to ask for a non-smoking table, otherwise you will be sat in the bar, which aside from chance of smoke, can be noisy (but fun). Also, take them to Green & Blue for a glass of wine before dinner. T
