I know I can eat a kids meal. Yum. Instead of some lovely, creative dish I can have a chicken leg or some nuggets. Yes indeed, that's an option I look forward to!! We do share meals. It's always a toss up as to who gets to order dinner and who has to eat whatever's being served.
We're often enough in the same boat of wanting smaller portions, but I have to disagree with you on this point.
I was just at WDW, and we were excited to see a VERY WIDE range of smaller portion items in AK. Among the quick serve offerings we saw:
Harambe- fruits, pastries, corn-on-the-cob, grape tomatoes, Greek yogurt, even pickles!
Tamu tamu - ice cream, dole whips
Mahindi - cinnamon glazed nuts
Caravan Rd - edamame, Asain noodle salad
Mr. Kamal's - hummus, falafel, tzatzki-topped fries
Yak Yeti - egg rolls, fried rice (a favorite), we also got a tasty ginger chicken salad and mini-mango pie!
Pizzafari - tomato basil soup
Terra- buffalo wings, hummus w/veggies, bag of rice chips
Satuli - the bowls offer tons of choices for $11.50 (beef, chicken, tofu, steamed veggies) or $13 (fish). In addition to choosing your protein, you also get to choose your base: salad, rice, or potato hash. Plus veggie slaw with all of the above. (see below)
Some kid meal options:
turkey wrap (Restaurantosaurus)
Eight spoon café- Mac N cheese plain, with pulled pork, or with shrimp
Flame Tree- chicken sandwich
Pizzafari - pizza or pasta = BOTH w/ choice of broccoli, grapes, or carrots
Satuli - cheese quesadilla, or a smaller portion bowl for $7.50-$8.50
I'm guessing you haven't been to Satuli yet, because the food options are very creative and completely custom to your tastes.
When we want something small, but meal like, we often look for items in the snack category, and many places now offer soup and yogurt.
In Epcot:
Japan has: individual sushi rolls, edamame, and miso soup.
Italy's Tutto Gusto Wine Cellar has: individual pizza slices, panini (5 options/$8 each/$14 for two),
small plates like: Arancini (lobster stuffed rice), meatballs
Plus assorted healthy daily side items like: awesome olives, white asparagus (w/basil), tomato salad, marinated artichoke hearts, caponata (= Sicilian eggplant salad)
Morocco now has an outdoor restaurant with abunch of small plate options! Among the small menu items: calamari, lamb sausage, Garlic shrimp, grape leaves, Brie fondue, fish Croquettes, hummus, and olives. There's also still the Tangierine Café next door with interesting side items like Tabouleh, Lentil Salad, and Coucous salad
Since you specifically mentioned
half portions of adult entrees, then I've got a great restaurant for you! the next time you are
at the Orlando airport, be sure to try McCoy's. It is part of the Hyatt. Just after you exit security, find the glass elevators/escalators in the big atrium and go up to the Hyatt's lobby level. They have all kinds of interesting small plates, half portions of entrees, soups, sandwiches, sushi, steaks, and EVEN interesting KID options! I'll warn you though, if you do order the 4ounce steak, it really is a 4 ounce portion!
