I recently had a 7 hour opportunity to observe Clark Airport. Clark has the makings of a good airport but attention to detail is sorely lacking. First of all there's free wifi - but only outside the airport (and maybe in Arrivals) airside you'll have to pay 800 pesos to use the VIP lounge. Airport tax as of 1 Feb is up to 600 pesos so don't spend all your local money! Then there's the bins - what bins? If you want a bin landside you'd better head to the restrooms. And while you're there bring your own toilet paper. There's no spray either. Airside (after you've paid your 600 pesos) there is toilet paper and some bins although they are few and far between. If you're downstairs where the "cheap" airlines leave from don't expect aircon or PA announcements. Upstairs there is aircon and PA but good luck hearing sufficiently to understand anything that's said in most announcements (Qatar Airways was the exception). So-called duty free stores are quite egregious here I saw packs of 6 beers with a normal retail value of 180-200 pesos priced at 500. News stand? Actually there was a small kiosk that at least sold a few magazines. Free drinking water? In your dreams. As for vegetarian food options - just head towards the exit keep going turn right and wait for the next jeepney back to town. Are there any good points? Well they do have seats you can stretch out on and it is reasonably bright and modern but it's not a nice place to spend any amount of time.
