The ones available in UK (glucomann/konjak only) have the mouthfeel to me very much like rubber bands. I don't think the ones made from half tofu/half konjak (which people say are more like real pasta) are available over here.

I sometimes make thin omelettes and slice them into noodle shapes to serve with pasta-type sauces or add to stirfries. I also use them cut into sheets for lasagne.
