Review of In-N-Out Burger

I ordered a protein style burger and fries. I told them it was an "allergy" and they noted it and changed their gloves. However, they thousand island dressing they spread on the buns (or lettuce wrap) was the same and possibly contaminated. The fries were undercooked and gross. I did feel sick afterward though I ate at another place earlier in the day and I'm not 100% sure which one it was.

Celiac friendly?
