MKingdom
Best - Cindarella's Royal Table (yes, overpriced but still worth it!)
Worst - Columbia Harbour House -- blechh the lunch given out for the Keys to the Kingdom tour. Suxs!
Epcot Best - Rose and Crown - Fish and Chips (hands down, we've eaten there every time since 1999)
Second Best WAS Alfredo's -- boy was that Fettuccini Alfredo awesome!
Worst - San Angel Inn (ambiance is great but food is awful)
Animal Kingdom- Best is Flame Tree
Worst - Boma breakfast buffet (just not worth the hype or price)
Hollywood Studios -- Best is Mama Melrose
Worst is 50's Prime Time Cafe
Resorts that I have sampled:
Boardwalk -- Best is the old Spoodles Worst is ESPN cafe
Grand Floridian -- Best is Victoria & Alberts (the chef's table was awesome on my honeymoon!) -- Worst is the Afternoon Tea (high price and little to show for it, service horrible)
Port Orleans Riverside -- really their food offerings are ALL bad (very fattening, everything is fried and unhealthy and expensive)
Fort Wilderness -- Whispering Canyon Cafe is best value (most food for your money at the parks and very nice taste too! You can take the free boat from MK to get here and back - worth the cruise!)
Downtown Disney --- Best -- We always eat at Bongo's (Gloria Estefan's restaurant) which never disappoints. Second best is (for lunch) Earl of Sandwich. I have 3 "worst" for DTD -- Wolfgang Pucks, Raglan Road (eww, nasty), and Fulton's Crab House (got sick from dinner there)
