Hi! I'm a newbie on this site but thought I would bite the bullet and reply to a post!
I have eaten McD's french fries loads of times without any reaction! When I was on holiday in the States (I'm from the U.K) this year MacDonalds was a god send! If there was any doubt where to eat there was always McD's!
By the way anyone got any suggestions for safe restaurants in San Francisco and Las Vegas as that's where were are going on vacation next year! I know there are a few Outbacks dotted around (love that chain! They actually knew what gluten free meant which is unknown in most U.K restaurants!) but would love to try some other "SAFE" places. Any suggestions would be appreciated!
