As stated on the other forum, La Paletta will be open on Tuesday 20th Jan, not Feb. Look out for their Sunday Lunch on 1st Feb. proceeds to the Easy Horse Care Rescue Centre.
There are a few Restaurants that do stay open all year, Dragon 2, Gran Mundo in G.A. Centre, the Patagonia in Sierrra Mar Square has also been open except for a couple of days at Christmas and New Year. A Tu Gusto has also been open although reduced hours in the week at the moment, still open late Friday and Saturday. I'm sure there must have been more but these are the ones we have visited most recently.
