We are going by ourselves to Versailles on Christmas eve and are wondering what to do about lunch. Very little posted here about where to eat. Other posters have recommended the expensive Gordon Ramsay restaurants (cheapest main at La Veranda is $39 US, cheapest main at Trianon is $82 US), and say that the restaurant at Versailles is lousy. We think it will be chilly for a picnic outside. Any more affordable suggestions?
