Cup noodle is my love

I do know that instant food is are not good for your/one's health, but I just can't stop eating it. Especially, my favorite one --- tom yum goong noodle. This spicy thai taste style noodle is absolutely addictive and has became popular in Tokyo quickly!

The Japanese food maker has factories in Thailand, so they can produce the authentic thai food. One of my friends in Thailand says that this is popular there, too. If you have a chance to go to a convenience store in Thailand or Japan, please try this cheap but awesome tasty noodle. I'm going to buy it again...

Well done! I love Tom Yum Goong as well!

 There isn't much to correct here; you did very well.

In English, we prefer to say, "not good for you" rather than "not good for [your] health"

Another correction: please try these cheap but awesome tasty noodles.

Finally, Thai should be capitalized.  *Thai not thai
