First of all, interior is superb! I'd give them a 6 star for the interior. Rustic industrial vintage feel with every corner being a photog corner. I think they can do a side job of renting it out as a photoshoot studio. It's that pretty.
Service: We came in at 2 pm the place was paaaacked! We couldn't find a single open seat. But after we wander off for like 3 mins we get to take over a table that a big group just left. With dirty plates still on the table though. Service was slow since there're sooo many people. She didn't even have time to wipe down the table after she picked up the dishes. After we ordered, we have plenty of time to take selfies while we wait for the order to come. Staffs are having a hard time looking for which order is what number. So just about 200 selfies later we get to eat our pretty cakes and matcha drinks.
We wanted the rose lychee but they ran out. We ordered other ones and they tasted just average. So 3 stars for average taste. They look really pretty tho, so 4 stars for prettiness. Items are also a little pricey but totally understandable so 4 stars for price.
Overall I think it's 4.3 stars. Totally worth the Instagram likes even though the food is just average.
