No! Disneyland has really good food these days. The sit-down restaurant in New Orleans square has wonderful food; my favorite is the grilled polenta with rattatoiulli and asparagus. (Not the Blue Bayou which has become insanely overpriced, but being inside the Pirates ride, is one of the coolest restaurants ever.) The gumbo shop nearby has surprisingly delicious gumbo, including a veggie gumbo. There are vegetarian options all over the park in fact. At California Adventure, there’s an Italian restaurant with good wines; the food court there has high-quality food of all kinds. And margaritas! I’ve been amazed at how much their food options have transformed over the past 5-10 years, as it used to be exactly as you describe.
And the pineapple whip floats at the Enchanted Tiki room remain as delicious as ever!
