Thanks for everyone's ideas. As always, our meals from Mark's were great, and we had enough leftovers for a couple of lunches, too! We carried out pizzas from Gizmos at Divi, which were edible but not great. Otherwise, we ended up managing to eat dinners out at several places where we could sit outside and made early reservations, when places were quieter. We also took turns taking her for a walk nearby while we were waiting for meals to arrive to keep her entertained—another advantage of all the outdoor seating. Not the long, relaxed dinners we usually love, but we managed without any meltdowns or annoying other diners.
