The first thing I noticed is that the (determined 2-3 hours) "supermarket" Ramen and the brand "A-One" the noodles are not really very good ... also there is a long strong artificial aftertaste in the mouth what is very unpleasant. (I'm a non-smoker for 3 years and had my taste buds regenerated)
The taste is all a personal question, therefore, I say to nothing.
The above points are my example at the Demae Ramen of "Nissin" terrible noticed, even they do not have such a strong artificial flavor ... (decays of 2-3 hours ...)
Therefore, I have now given away the A-One's, and am going in the future only the Demae Ramen by Nissin order (I'm still the "Top" version of Nissin try)
