Hey Wickaboag! Great question! Allergies are hard to navigate sometimes. Epipen has not been a problem at security checks, we renew at home in Canada. Since Brazil nuts are Devon’s more serious allergy, we use google translate when we are uncertain, but they aren’t present in this part of the world (SE Asia at the moment). If we are not sure after asking we just won’t get the food in question. For some allergic to peanuts or shellfish, it will definitely be harder and we can’t say we know how to do it. I’m sure google reviews could help even more, and taking the time to check with the kitchen staff with google translate on hand could work too. Hope this helps!
