Language Exchange Meetup

Last evening, when I was heading to a grocery store nearby(sounds more fluid to say "heading to a nearby grocery store", but that is okay.), I bumped into a friend with his two friends whom I had never met. Since it had been a while since I had seen him, we started having a small conversation on the street. At the end of that, he invited me to a Meetup which they were heading to.
At the time, the time was already 9pm passed, but since the location was nearby, I decided to go there.

The Meetup was held in a food-coat of a mall nearby. There were about 15 people already gathering. The concept of the Meetup is was language exchange. 50% of Japanese learner and 50% of English learner.
I sat on a chair available between 2 of Japanese women, then initiated a conversation.

After having a nice conversation, I was invited to watch Godzilla next Tuesday, which I gladly accepted it.

Great work! Your english is excellent. The only thing I would say for improvement is, try to focus on keeping it past tense the whole time, if you're writing in past tense.
