Looking for dairy-allergy friendly restaurants

My little cousin is allergic to all dairy edit: AND eggs. (including things with eggs baked in them.) I’m looking for places that could be a good option for her that has a kids menu/good menu for kids? Vegan restaurant suggestions would be great - but she also can eat meat/loves chicken nuggets and such. Is there any place that serves meat but also is vegan/dairy allergy friendly?? Maybe too specific of a request.

Also any great vegan dessert recs would be amazing :) she’s visiting the city to see a show - so around midtown would be ideal but we can go anywhere in Manhattan. She’s also sleeping over so if there’s a particularly fun/good place I would love to bring her anywhere around the city.

Thank you!!
