I seem to hear a lot of bad reviews on PH, however we have eaten there in 95, 98, and just this past August, and we have always had a good meal there. In fact this last time it was great. I had the LA Lasagna which was excellent and DH had the chicken, broccoli & pasta dish which was very good too, but the pasta could have been cooked for maybe 1 more minute. The kids had pizza which was typical kids meal pizza. Our neighbors were with us and when they first saw the menu they thought it looked a little over priced. By the time they finished the meal they thought it was well worth the price. I cant remember all they had(their kids eat adult food) but I want to say they shared a fajita, surf & turf, salad, and something else.
We were all very pleased, and my family is planning to go back again in July.
And Im not sure where Disney Quest was, but we walked to PH from the Marketplace, so I would guess since DQ is in the West Side it would all be in walking distance.
