I don’t like Vigan food. It’s mostly deep-fried greasy animal pieces, like pork belly and sausages that resist description. I don’t see people visiting the Philippines for the food.
Vigan, the city, is very pleasant. Its entire downtown has completely preserved Spanish colonial architecture. A Spanish traveler I have met has felt right at home, right down to the details. Except that many of the buildings could use a touch of paint and maybe a roof. The weather is balmy and sunny. It does appear that the city’s entire Internet traffic, including mobile, runs through a single slightly psychotic router though.
