Hi, I am the owner and Head chef of the business, and I am the one who make entire vegan cheese for cooking. honestly First of all, to make you sure about 100% vegan cheese? We invite you to our production line of our vegan cheese processes. Secondly, about your Allergic Lactose Intolerant, Please make sure what you have it in all day before visiting Because having one bit makes you vomiting? that to fast . at-least every food need minimum 2 to 3 hours to digest or 45 min to 90 min you make vomiting. May be you eat something at another place? you know better. We spoken with our manager, and he showed you the entire cheese ingredients. to make you sure, so i dont find any reason for this one star review. thanks Kayjus Singh Owner/Chef EL CAFE, Vietnam
