No buffet option, just a menu to order from. The list price for the continental is 190 pesos, the "full" breakfast is 290 pesos. Continental breakfast is just a small plate of fruit, a tiny cup of yogurt, and a basket of bread & pastries. Didn't go for the upgrade, nor did I check to see whether I could get a 190 peso credit towards other items on menu (they had some hot food options for just 130 pesos).
