Well, I am going to opine here both because it might benefit others a tad, and because I would like more clues....
My daughter is now 14, amazingly picky in ways, yet with broader tastes than most of her peers. I can get her to many different ethnic restaurants, but she clings to very few menu choices for each nationality. I have not managed to get her into Mexican/Latin American cuisine at all and could use some help in that regard. I had always thought Casa Mexico's melted cheese appetizer and cheese enchiladas might do the trick, but they are gone.........
Anyway, here is what she likes. Maybe other kids would also find these renditions appealing:
Sweet and Sour Chicken. She likes them best at Yangtze River in Lexington. (These are also on their night-time buffet. If we go to that, she will also eat beef and broccoli, broccoli in oyster sauce, chicken wings, spring rolls [which I think are dreadful, but which vary a bit], bananas [theoretically crystallized I think, but just in sweet syrup], maybe a few more things.) About a month ago, the ones at Sichuan Gourmet in Billerica were also to her liking.
Peking Noodles. She ONLY likes Qingdao's rendition.
Dim Sum. Usually at China Pearl. (Pork Buns, taro balls, various other savory pastry-type things, egg tarts.)
Tamago Sushi. She will deign to try them at most places, although her (and my) favorite rendition was at Typhoon on Boylston St. in Boston (does that even still exist?).
Unagi Sushi. No particular favorite.
Chicken or Salmon Teriyaki. Her favorite chicken version is at Asiana Grille in Arlington; one of her favorite things is the CT lunchbox, unless they omit her beloved pan-fried noodles. (She used to like the salmon there, but it went downhill.)
Pahd Thai. Favorite: Lemon Tree in Burlington.
Mu (sp?) Wan. Favorite: Dok Bua.
She will also eat some Panang and choo chee curries if I order them.
Chicken Tikka Masala. Favorite: Bollywood (Lexington). Also will eat it at Gourmet India and, now, Namaskar.
She will also partake of kormas and a few other nonvegetarian things when I order them.
Naan. Several places.
Gulab Jamun. Several places.
Bulgogi. Used to like it at New Jang Su Korean BBQ Restaurant (Burlington) but decided it (possibly all renditions) is too fatty.
Roti Canai. (Penang.)
Chicken Curry. (Ditto.)
More Generally Available Asian Stuff:
Tempura. Used to like it at New Jang Su Korean BBQ Restaurant (Burlington), but they changed their rendition. She will eat sweet potato done this way, although she normally will not eat sweet potatoes.
She also like Holy Smoke(s?) because they serve popcorn instead of bread. :-)
What dishes have other parents used to lure their kids into interesting restaurants?
