St. Kai

A fantastic cafe located in Mortdale. The coffee is super great, the service is friendly, and the food is beyond expectation. Highly recommend the tiramisu latte and tonkatsu rice bowl. Will definitely come back and try other dishes!!

Nice little corner cafe, close to Oatley Park. The burger is so good paired with fried eggs. I love the ramen especially the nutty soup, so yum. Their coffee is also very impressive, highly recommend the set, we got the long black, piccolo and orange juice long black.

Visited St. Kai for a Japanese brunch and it was absolutely delightful. The Yemen microlot Jarmah Natural coffee was a standout with its rich flavors of raspberry, black currant, and lemon plum—truly a rare find. The Tiramisu Latte was perfectly sweet and indulgent. Don't miss the Tantanmen ; its the best！The ambiance is cozy yet elegant, making it a perfect spot for a weekend brunch. Highly recommend!

i really like this local brunch with a japanese twist. Great vibe and nice affordable food. I highly recommend ramen and tonkatsu. Their coffee is good too

Chill cafe with good food and drinks menu.
Serves specialty coffee and Asian fusion food.
Vibe wasn’t overly busy and quite chill.

Very Yum fried Pork on rice with avo bagel, the coffee is amazing as well.

What a lovely cafe! Great coffee and such a cool atmosphere. Would recommend to anyone in the area

This is not your typical suburban cafe. The food is, what I would describe as, Japanese inspired ModOz. The dish I had was excellent. While simple it was well made and presented. The coffee was excellent. Staff were pleasant and professional. All in all a very pleasing experience and I will be returning to try the ramen. Update - I returned and tried the ramen. It did not dissapoint! Next will be the Donburi :-)

While the place is quite pricey, I believe it’s for good reason.
I ordered the wagyu patty brekkie roll ($16). It was delicious, and since I was absolutely famished, I finished the thing in under ten minutes. Fatty gooey goodness. I couldn’t take a photo since I dug in right away.
As for the coffee, it’s ridiculously good. Probably the best I’ve had in a long time. Post-covid times have rendered many of my favourite coffee spots mediocre. I’m so glad I finally gave this place a go, I will definitely be revisiting. My large oat latte with an extra shot was appreciated even by my sister, who hates all non-dairy coffee. If you like cold brews ($9, nitro), you really need to try this place.

Unique and chill cafe tucked away in the quiet suburban streets. Coffees were very smooth. Really enjoyed the filter coffee and bebop coffee. Both the sandwich and brekkie roll were delicious. Definitely keen to come back and try more items from the menu.

Service is friendly and warm, food and coffee is also nice.A good place to chill

The rice bowl and coffee are sooooo nice.

I love the Tonkatsu donburi, so interesting flavor! And the service is great, definitely gonna come back

Good local spot to chill out. Nice coffee&food. Lovely staff. Will come back again!

Lovely Japanese inspired cafe. The food is delicious and the staff are friendly. I had the Tantanmen (see photo).
They also have weekly specials that they call “Research and Development” 😄
They appear to be dog friendly as well, although I didn’t have my pup with me at the time 🐶

Great Japanese inspired neighbourhood cafe in Mortdale - serving good food with friendly service. Cozy place so it can get busy on weekends.

This was a bit of a drive out of the way, but absolutely worth the trip. The vibes are good, the menu offers up plenty of fun twists for fan of both typical brunch fare and Japanese staples like ramen and donburi. The roster of beverages available is similarly diverse, so be sure to get experimental. St Kai's is easily one of the best cafes in Sydney right now. Strongly recommended.

Have an amazing breakie time with my family in Sunday morning! Simple internal renovation but cozy vibe. I love the shengye Latte so much ☕

Amazing Japanese-inspired brunch cafe tucked away in a quiet corner in Mortdale. Visited twice and the food was fantastic both times. Really enjoyed the clean, minimalist vibes of this cafe as well as the Japanese touches in their decor (loved the anime art). Their menu is small but changes up from time to time, so I'd gladly revisit in future to try more of their items!

If you're looking for a hidden gem, St Kai is the place to go. First of all, this place is busy for a reason! Great family owned business with charming service and just downright delicious food and good coffee. Okay so I’m a local which makes me bias but credit needs to go where credit is due! Keep up the great work St Kai :) ps their burgers and noodle dishes are a must.
