Please, try to keep your comments focused solely on Disneyland Park, Disney California Adventure Park, the three Disneyland Resort hotels, and the nearby Downtown Disney District.
Dole Whip (well, that obvious)
Monte Cristo Sandwich at Blue Bayou
Bodin Bread Bowl with soup
I would make sure to try Blue Bayou. The Monte Cristo sandwich is great and is defiantly an classic Disneyland experience. DCA has a nice food court-ish area by the Bodin Bread Co. which has burritos, noodle bowls, and MARGARITAS!!!!
One of the few things I do remember from my last visit is the Monte Cristo at the Blue Bayou. However, the prices seem to have gone up drastically since the early 80's! But that's the price you pay for such great atmosphere, I guess.
It is worth noting that Cafe Orleans near the Blue Bayou also sells the Monte Cristo for about $5 less... and supposedly their pommes frites are worth the price of admission. Anyone tried them recently?
Downtown Disney has some good places too, but most are not as memerable as the inside of the parks. Pizza Napoli is probably the best out there. ESPN Zone is pretty good too, but a bit chainy.
One thing to note is that Downtown Disney does not stay open as long as it does at WDW. We had a problem getting a late dinner after the parks closed at around 10pm. Only ESPN Zone was open.
But my favorite food there which is not as "well known" is the Bodin Bread Co. Cafe which gives you sandwiches on freshly made bread and bread bowls filled with clam chowder, chili, or another soups.
I was greatly impressed with that little grouping of table service places right by the Pacific Wharf Cafe. All the food there has been above average (even for Disney). You can get Sandwiches, Soups in Bread Bowls, Asian Noodles, Tacos, Burritos, and a Margarita Bar!
Thai coconut curry tofu at Lucky Fortune Cookery at California Adventure
Chicken panini at Wine Country Trattoria at California Adventure
Chicken fusilli at Red Rocket's Pizza Port at Disneyland
Plantation Roast New York salad at River Belle Terrace at Disneyland
I am not much into Tofu, but I am curious about the Lucky Fortune Cookery. Have you had either of the Asian Rice Bowls with beef or chicken? Are they pretty much similar to what the Tomorrowland Noodle Station used to slop into bowls at the Magic Kingdom?
The chicken panini sounds awesome... and I think you did a review of it at one time, a while back. Have you ever tried Trattoria's Caprese Salad? I love a good Insalata Caprese!
I have not heard a lot of good things about Redd Rockett, but generally the discussion revolves around the pizza. On the other hand, that pasta dish you mentioned sounds excellent. The Tomato Basil Pasta also sounds intriguing.
As for the River Belle Terrace, have you ever visited for breakfast? You probably already know this, but rumor has it that the River Belle is where Walt used to eat breakfast every morning. I guess the "Steamboat" reflects what he used to order. Anyway, have you had the Roast New York sandwich? It sounds interesting as well...
Keep 'em coming gang!
Also almost anything on the House of Blues menu is worth a try.
I'm not a fan of the doughy crust on Disney pizzas, but the creamy pesto sauce on the fusilli is dangerously addictive. And they top it with actual grated Parmesan - not dust from a green can.
I can't remember the last time I had breakfast at Disneyland. It's been ages. Gotta put that on the to-do list.
