Wow, I have recently had an experience regarding a food allergy and a restaurant.
I was on vacation at DisneyWorld and on Day 3 we went to eat at the Yak and Yeti in Animal Kingdom. We ordered the Mahi Mahi. Here is how it is listed on the menu.
"Crispy Mahi Mahi - Filet of mahi mahi, Japanese bread crumbs, Cantonese sweet and sour sauce, jasmine rice and stir-fried veggies. - $19.99"
I am severely allergic to peanuts. Since this was a new restaurant, I had my boyfriend taste the food first. He thought the sauce was questionable and we ended up asking the waitress if there were any peanuts in it. I took her word for it and ate a couple of bites of mahi mahi dipped in it. After about 5-10 minutes I knew i didn't feel right. We tried to make it back to our hotel, but I didn't make it. On the bus ride over I had to get them to stop and I ended up getting sick in some bushes in front of everyone. The bus left us. I felt dizzy and my heart was racing. I was having an anaphylactic reaction but luckily did not go into shock. Eventually, we got back to our hotel room and I was doped up on Benadryl and slept for a good 6 hours. I was also beet red. The next day we were going home, so essentially that one meal ruined our whole day and we were only there for 3 days total.
I just think that the wait staff should be better trained in matters like this and should be more careful. I did call WDW to complain about this, but never heard anything back. Even though I did learn my lesson (I should ask the chef straight out), I think restaurants should be more careful and educate their staff better.  |
