という店もあります meaning in that sentence?


I don't get the meaning of という店もあります in that sentence. I understand: "This
month sales were 10 times higher than the sales from April last year", then I
have no clue for the end of the sentence.

> 今月の売り上げが去年の４月の１０倍になったという店もあります

My guess is:

> "This month sales were 10 times higher than the sales from April last year
> for one of the shop".

By the way, this is the complete sentence:

> 大阪ではタピオカを入れた飲み物を売る店がたくさんできていて、今月の売り上げが去年の４月の１０倍になったという店もあります。

Can you guys help me please?




The main clause of this sentence is simple:

> 店もあります。  
>  There are even/also stores.

And there is a long relative clause modifying 店. This という is quotative-と
followed by 言う, but is a very common combination used to describe a following
noun. See [my previous
answer](https://japanese.stackexchange.com/a/52003/5010) for examples. In this
case, you can use "where" or "in which".

> ～という店もあります。  
>  There are even stores where ～.

Therefore:

> 今月の売り上げが去年の4月の10倍になったという店もあります。  
>  There are even (tapioca) stores where this month's sales were 10 times
> higher than the sales from April last year.
