1- If you are in a premium resort (Lopesan Hotels or Riu Palace)… there. Gold by Marina Hotel also have a very nice breakfast. Note that if you´re not a guest there, you can still enjoy their breakfast (simply by paying of course. They are unlimited buffets so the price is on the steep side).
4- Mardi Gras at Yumbo for an English breakfast.
5- Flor de Vainilla in the local neighborhood of San Fernando for an Italian/French breakfast (delicious croissants and everything else on the menu is exquisite !)
At all cost, avoid Cafe de Paris, a tourist trap with terrible quality and pricing.
