Misleading menu

I consider myself a regular at Hunga Busta's and only recently have I discovered that they do not clearly state the ingredients and products in their food. i have purchased their chicken gatsby on numerous occasions with the belief that there is only chicken in this product however it came to my attention only after inquiring that there is actually mutton or beef products that gets put in this item when it is made. i find this to be very misleading as the menu does not state that in a chicken item there would mutton or beef included.
