I'm shocked you were told to cancel your res. We ate there 8 days ago and after noting the allergy (milk, egg, peanut, treenut) on the ADR and submitting the food allergy form to Special Diets, no one called us about any restaurants being unacceptable.
That said there is reason for concern and I can understand some families choosing not to go there. After reading rave reviews from other families with allergies we decided to try it. It was, from an allergy perspective, the best dining experience of the week.
My DS (4.5) didn't even have to get special, separate food (except for dessert) like at other places. Chef TJ talked with us personally. He suggested, as we'd already planned, to skip the peanut sauce for the entire table. Other than that, DS was able to eat everything BUT the pork dumplings and bread (and those may have been due to his milk and egg allergies). We also skipped shrimp at our table because DH is shellfish allergic. The salad was safe, the brocolli and noodles (egg free!!!) were safe. All the skewered meats and the other two sauces served were safe.
For dessert, Chef TJ brought DS the most amazing tower of goodness. I almost cried.
