My teens are now 19 and 20, so I have some experience with this, as we’ve been taking them for years and always do Free Dining, so have lots of TS experience. My kids are not super picky, but my daughter is a vegetarian, though she does love seafood.
in MK, BOG, of course, is awesome. The Ballroom has windows that has active snow outside - forget the Beast, this castle meal is awesome, just for the atmosphere. But it is hard to get. We have been to Skipper Canteen, but I’d call it adventurous, honestly, and wouldnt waste my money on it.
in Epcot, I second Teppan Edo - what we call “CHOP 'EM UP” this can be steak, chicken, shrimp or possibly tofu. Such a good meal, and teens love Chop 'em up! The chefs are great and put on a little show. Great food. Via Napoli is very good and best not on dining = large pizzas are HUGE and you can feel like you are eating “foreign” food = its in the Italy pavillion. Also, Chefs de France has a very good menu - steak, chicken, vegetarian entrees, and provides a nice “fancy” meal that is not too fancy.
AK I totally recommend Yak and Yeti - if they like “chinese” food. In fact, we’ve only done the sit down once, and though it was very good, I think we will go back to the chicken fried rice and egg rolls from the counter service. There is a great little seating area in the shade behind it - we use snack credits when on dining and this allows us to double up for a Signature meal.
HS - yeah, we dont sit down to eat there.
The Resorts are cool, though, for teens. They are all so different and are fun places to explore and depending on the season, there may be activities to do there, too. For example, Definitely go to AKL to see the animals, preferably at night with the night vision goggles. BOMA is a GREAT BUFFET where your little veggie will feel super special as the chef takes her and explains every vegetarian dish to her. There is different interesting african food to taste, but also delicious salad bar, prime rib carved, and comfort food. It’s pricey, but worth it. The desserts alone I could eat for a half hour!
Also, we LOVE Ohana - for dinner especially - they will likely not participate, but younger kids do some games and stuff and if you get a good table and the right time reservation, it is a beautiful place to see the fireworks. Yes, it is skewers of meat, but if your daughter eats shrimp, she’s good to go. I’m pretty sure there are some good fresh interesting salads as well? but you better check that menu.
If they like sushi - at all - there are fun places for that, too.
Disney Springs also has fun selections - we loved Paradiso 37 - its menu is huge, surely something for everyone. Also, if they like Music, the House of Blues is also a fun hangout.
Teens and Disney are awesome! Mine have really enjoyed and are now hoping to go as “adults” on their own. Happy Planning!
