Unfortunately my honest opinion is that this is not very suitable for foreigners.

There were mostly locals who appeared to be regulars inside. They did not have an English menu. It was quiet except for some chatter between the locals and the owner and barista of the shop. It was also confusing (due to the setup of the interior) whether I was supposed to approach the counter to order or to wait until they came over, and I was not really guided or given instructions until they saw me looking very lost.

If you do plan on coming though, I think you are supposed to find a seat, call for the staff (who is the mother of the barista) to take your order, and wait to be served.

Regardless, I felt the coffee was really good.

Even though I did not feel very welcome, I recognize that this place is probably very valuable for the locals. It seems to have a bit of a community/neighbourhood vibe, and serves as a place for the locals to have their coffee/brunch and to sit back and relax.

Hence, I will give it 5 stars. But if you are someone who is easily anxious like me, I would suggest you go somewhere more touristy and open.
