Foods and places are plural so you must make sure all references to those words (ie. These, them) are plural

“Butaman” means pork mince-filled steamed buns.

You're right that the word before “filled” should be hyphenated but because “pork mince” is two words it gets a bit difficult and it's easier to just rearrange the sentence a bit.

Thise cheesecake at this store is so flurrffy.

We haven't explicitly mentioned cheesecake yet (the title doesn't count) so instead of saying “this cheesecake” (what cheesecake?) we say “the cheesecake at this store/sold here/at Uncle Rikuro’s/whatever descriptor you want is so fluffy.”

Fluffy - ふわふわ
Flurry - 小雪 (there are a few other definitions but I think you meant “fluffy” here)

ThisKukuro is a delicious takoyaki restaurant!

In Osaka, tThere are many takoyaki restaurants but my recommendation is definitelyin Osaka, but I definitely recommend this one.

Seperatin “In Osaka” out at the beginning marks Osaka as the topic of the sentence. It's kind of like you're saying 大阪には instead of 大阪に. Its not wrong, but it puts too much focus on Osaka, if that makes sense

It's usually better to use a verb than a more complex object phrase.
Ex. I think you should take the course >> My thought is that you should take the course (not incorrect but awkward)

You can’t wrong with herethis restaurant!

Because "These" is plural, you need "some" here instead of "one." (Compare: "This is one of the most famous...")

This cheesecake is so flurry.

Maybe you mean "fluffy"? Like, very soft and airy? "Flurry" usually means a swirling something, so more of a movement. (Like a "flurry of snow").

This main store is also located in near Dotonbori.

"in" and "near" can't exist together in these sentences, because "in Dotonbori" would mean it's inside the city, whereas "near" means it's not inside the city. :)

There areis a symbol that is called Tsutenkaku.

If there is one symbol, then "There is a symbol..." If there are many symbols, then "There are symbols..."

In addition, there are very famous for Kushikatsu.

I'm not sure what this sentence refers to. If you are saying that the place is famous, then "In addition, it is very famous for Kushikatsu."

You can eat them by dipping them in the sauce.

This shop is also in near Dotonbori.

You can see beautiful scenes in ry there.

"Scenes" is not wrong, but I think "scenery" might be more appropriate.
You can say "you can see beautiful scenery here," but it sounds more natural to me to say "there" if you are not yourself writing about this from that place. :)
