In the "old days", if you just turned up at PH, then you were in for a VERY long wait, and the chance you may not get in at all. The line used to be immense!
However, in recent times, PH now appears in the "top ten WORST places to eat at Disney" and its popularity is severely diminshed. I last ate there in 98, and it was truly awful and expensive.....you dont often get a bad meal in the states, but I have to say this wasnt good. They seemed to be capitalising in on the fact people would put up with bad food just to eat with some old movie junk......recently though, we are all wising up! They cant serve cold/poor quality/bad tasting stuff and charge a fortune for it.
I did hear that the menu has been revamped, and Im sure you will get tons of replies to this thread with positive opions of the place. I have to say, personally, I could name you 20 other restaurants on Disney Property where you could eat a whole lot better for the same money.
If you want to go for PH, then a reservation for lunch isnt needed, but you might want to book something for a dinner to omit having to hang around for a table. Be wary of the "dinner packages" as it can work out more expensive if you just want a burger and no appetiser or dessert.
Hope you enjoy your stay!
