Stopped by after a long night out as it's open 24 hours and we were staying in PH. It's a large restaurant with plenty of comfortable seating, but that's pretty much all it has going for it.
Did not enjoy my experience there. Food was way overpriced, service was slow (waited 30 minutes for our food, and this was at 3am), waiter forgot to bring toast with my buddy's breakfast, and the waiter was being a smart ass - all I asked was if I could substitute fries for something else with my chicken burger, and the response was "be creative". Save your money and frustration and head over to the Earl of Sandwich in the hotel if you're looking for a place to eat in the hotel that's open 24 hours.
