I can safely say that the night life of Vigan City is not all about the disco lights and party. Partying with food is even more vibrant than partying in bars and disco houses in Vigan. Being a religious city which has become the religious center of the Spanish colonial period, partying in disco bars over night is not so common for "most" of the people in Vigan.
Vigan is a conservative place, generally speaking. Every antique house can be linked to Catholicism brought by the Spaniards.
The feeling is so very soothing eating in an open air under the neon lights and the stars in the sky with friendly strangers and the smell of the food being grilled while waiting.
However, take your time to eat, you might get choked. Hehe...
