I love Monster Mash. The premise is simple.....you choose your mash, you choose your sausages (and the number of sausages, they are huge so go easy) and you choose the type of gravy that you want. It's simple, honest, old school british food.
It's relatively cheap, about £6 for your meal. They serve tea in mugs, not cups and the decor is 1960s british cafe; all lino tablecloths and tomato shaped ketchup dispensers....fab!!
They have other food on offer e.g. macaroni and cheese, pies etc but to be honest I have never tried anything except the bangers, mash and gravy simply because that is what I go there for. YUM SCRUM!!
