A friend of mine quit her office workjob and started thea cafe business.

In the menu of her cafe, mMainly healthy food and drinks are included.offered on the cafe's menu.

sounds better like this

But not onlyIn addition to food service, she's going to make the cafe community-based /multipurpose, so that she and the area residents can have various kinds of events using the space in the cafe as well.

IOn Saturday afternoon (yesterday), I provided a hand massage to the customers in the cafe.

Another friend provided a fortune-telling by Tarot.was giving customers tarot readings.

"tarot readings" is what you were trying to say

One of the customers requested the friend as the cafe owner to have a meetup for language learners and an event for visitors from other countries to join easily join.

Since you said above that your friend owns the cafe & that it's community-based, you don't have to repeat who he is giving his request to, since it's already known.

I suggested that she should place an ad on the internet saying that the cafe is a place where overseas tourists can easily ask for the directions and talk about anything when they are in trouble while they stay in Tokyo.

I'm excited whenabout what I think what the cafe will be like 😁

A friend of mine quit her office workjob and started thea cafe business.

"office job" is the common noun phrase to describe a job at an office.

"a cafe", because "a" is used when we are talking about a cafe in general. We also do not need to use the word business, because it is implied that a cafe is a business. For example, we could say "he opened a store". We would not need to say "he opened a store business".

IOn the menu of her cafe, mainly healthy food and drinks are includlisted. ¶

On her cafe's menu, mainly healthy food and drinks are listed.

The common phrase is "on the menu". For example," What's on the menu for tonight?"

"of her cafe" is okay, but it can also be rewritten as possessive "On her cafe's menu"

"Iisted" is used, because it means what is stated on the menu.

But it is not only for food service, s. She's going to make the cafe community-based and multipurpose so that she and the area's residents can have various kinds of events using the space in the cafe as well.. ¶

"it is" needed to refer back to the cafe and provide a missing predicate. "for" is a preposition to refer to what the cafe is used for.

"community-based" and "multipurpose" are two separate words, so we use "and" to separate them.

"area's residents" we need to show possessive that the residents belong to the area.

I deleted "in the cafe as well", because it is already implied that the cafe's space is being used, since you mentioned it will not only be for food service.

IOn Saturday afternoon(yesterday), I provided a hand massage to the customers in the cafe.

"on" is used whenever we talk about days. For example, "I'll see you on Monday." "The meeting is on Friday."

Another friend provided a fortune-telling bywith Tarot cards.

"fortune telling" is an activity, so we do not need "a".

"with" to refer to what your friend was using, which are "Tarot cards".

One of the customers requested the friend awho is the cafe owner to have a meetup for language learners and an event for visitors from other countries to join easily.

"who" is a pronoun to refer to your friend.

I suggested that she should place an ad on the internet that the cafe is a place where overseas tourists can easily ask for the directions and talk about anything when they are in trouble, while they stay in Tokyo.

"the" is not needed, because we are not specific about directions in this case. Example would be "Please give me the directions to get to Tokyo" compared to " I'm lost so I need to ask for directions".
