Hello BlueJasmine, how's life treatin' ya?
Umm, I'm sorry, I don't want to burst your bubble but I have to agree with DVCconvert above me.
Over the years my family and I have been to Planet HollyWood a few times and I have to say that it is not one of our favorite restaurants. The food is okay, it's not bad, but you're not going to sit there and say "HOLY ---- THIS IS AWESOME!" ... the food is par and overpriced.
Now, overpriced food at Disney or the Disney area is nothing new and not even a surprise for first timers but usually you have something in the way of atmosphere to make up for it. In this case I DON'T think that the atmosphere makes up for the high price of the food. LuvLuvLuv was correct in saying that it reminds me, sort of, like an AppleBees ... some stuff hanging on the wall but nothing super impressive.
But listen ... this is YOUR vacation and if you really want to try it PLEASE do not let me or anyone else talk you out of it! These are OUR opinions ... apparently other people must like going there or it would have went under years ago. It sounds like you have been to another Planet HollyWood in the past ... if so you know the score ... whether it's a McD's here or there it is still a McD's.
However, since you are right in DownTown Disney anyway I WILL recommend RainForest Cafe and T-Rex. Not only is the food there better but, I.M.H.O., the atmosphere is head and shoulders over P.H. and more than compensates for the pricey food!
I hope my opinions helped in some small way! Should you have any other questions I am at your disposal!
Take Care & Be Safe!
