I didn't keep track but they were "native" concoctions though. Really, food is food. Maybe different spice "mixtures" but the same as here. Noodles, lots of seafood (fish, shrimp etc). Pork and chicken are by far the most popular . Lots of veggies. Not much beef if any. No dog or cat that I was aware of although those are more popular in say, Viet Nam.
Thinking back, I wish I had taken pics of menus but didn't. But sometimes you want something familiar too. My daughter had pizza . When we were in Tahiti, we just had to have a McD burger & fries. I don't eat McD here at home but just wanted something I was familiar with and not experiment.
When you look at Philipine recipes, they're really not all that different (other than maybe some odd ball ingredients.) I'm going to be making a chicken dish

in preparation for guests (I've not made this before) but if you look at it, again it's just the combo of spices.
If I come aross a PHP recipe that uses an odd ingredient, like most of us I would try to find a suitable substitute for it. That chicken recipe calls for calamansi juice (but then says you can sub lemon juice). Just one example.

For another example: Pad Thai. No respecting chef would use ketchup in but I've found some "authentic" recipes use it IMO. But those same recipes don't use tamarind. I consider tamarind one of the essentials in it. Go figger.
