I spent a few days in El Nido, but I couldn't find a few cost-effective restaurants. The prices here are much higher than I imagined or thought of in Southeast Asia.
SQUIDOS is a very lively restaurant at night. I always hear people singing. It should be classified as a restaurant bar.
The American set meal is good, apart from the price (it seems to be 350 pesos), and the mango is very sweet.
