According to one of the sushi chefs behind the counter at Bikkuri, there are no peanuts or nuts used in any of the menu items at this popular King Street East resto. Of course, seafood is also a common and serious allergen to be aware of. From allergy testing, we already know seafood and other types of fish are safe for DJ, so this is one restaurant we may try with him.
Always do your own research before eating out with a severely allergic child. Call ahead and speak with the restaurant owner or chef, remind the staff once you arrive. Ask once again before you order and when the food arrives. Always carry an epi-pen, medical information and a cell phone. Understand there is always a risk.
