I can really relate! We miss eating out probably the most... but BK is one of our SAFE fast food places. Primarily because, like someone else mentioned, one of the BK execs was as the FAAN conference and is a big supporter of proper and complete labeling as well as staying away from the big allergens with all BKs products. We were assured NO PEANUT products would be used. However, I ALWAYS check anyway just in case that guy isn't with BK anymore and they changed their ideas!!! or if the francise decides to be original!!
Also, BK offers full ingredient lists to anyone who asks ... usually. One of the few companies to have printed lists available at the restaurant, in my experience.

Gracie, this is off the Burger King topic, but a response to what to bring. We are in the habit, since a trip to San Francisco, for which we got this great collapsable lunch cooler, of simply packing it everytime we leave the house for an outing.
I actually put stuff in it for both of us, especially was great when I was doing weight watchers and wanted to avoid the fast food. I throw in gogurts or yougurts, various fruit cups which come in individual sizes, fresh fruits, crackers, pretzels, favorite cereal in a baggie, nutrigrain bars, cookies, soy butter sandwiches(but yours is young, maybe for that). In the days when she was less picky: mozzarella string cheese sticks, pieces of chicken or turkey, etc... It seems like a pain, but it really is a habit, now and we just do it. Everybody has a healthier snack, we save lots of $$, and I always know we have something safe with us. Just rying to offer some suggestions! HTH. becca
