Hello if you are going to Clark/Angeles City for food tripping here are some of my recos:
Go to Makimura if you want some ramen, even japanese tourists likes it. They have some branches in SM clark and Marquee Mall but they have an Al fresco stall in Balibago that stays open up until 2 am.
If you want some sisig look for Milas, they have branches in Nepo center and in Korean town
If you want korean go to Seoul grill in Clark near Royce Hotel and casino
If you want some good fried chicken that has a different taste from your usual Jollibee, KFC etc look for Angeles Fried Chicken, and I highly recommend their gambas.
If you want some authentic chinese then Fortune and Friendship Garden are your go to places.
If you want some late night sushi with very generous servings look for Tamla in korean town.
If you want a one stop shop for pinoy street foods (fishball, kikiam, mami etc.) look for toto bits, its a cluster of stalls in Nepo Center that is very popular among the locals.
I'll try to update if I remember additional places. Enjoy
