You definitely want to visit this Mermaid cafe in Bangkok Thailand


Wipe away your mermaid tears because are you ready for this? There is now a mermaid cafe to fulfill your underwater dreams!


The first cafe that opened was called the Mermaid Island Cafe in Rangsit in Pathum Thani province (outside of Bangkok).

But now the Pathum Thani cafe is under renovation and they have just opened (in August 2017) a larger ‘castle’ in the heart of Bangkok! Now it is called Mermaid Castle Siam at Siam Square, which is near MBK and Siam Paragon.

That makes me super happy because it is so convenient to get there!


Not only that, there’s FOUR floors dedicated to all things mermaid.

The first 3 floors are for shopping, where there are mermaid related clothes, bags, jewellery and makeup. The cafe sits on the 4th floor.


While the Unicorn Cafe had plush sofas, the mermaid cafe is a little less luxe, with pink stools.


I LOVE how they have a Villain Zone for those who prefer the sassy Ursula over the wide-eyed Ariel.

Their desserts are multi-coloured just like this green and pink waffles.

Uber cute fish tail cupcakes! I want one in every colour! Their shapes look so hyper-realistic too.

Wait hold on, I think we’ve mixed in the wrong Disney movie here. Is this part of the script?

They also have mermaid tail blankets for you to chill while sipping your milkshake.


This photo above was from the old cafe at Pathum Thani. To be honest this one looks cozier than the other, with lots of plush pillows and pretty gauzy curtains.


Even dogs weren’t left out from the underwater world in the Pathum Thani cafe! No word yet on whether the new cafe in Siam Square also has dog-sized mertails. (Update: there are merdog tails at Mermaid Castle Siam!)

Of course, if you prefer to skip the cafe and get down to shopping, there are lots of pretty things to look at! I really want a fluffy shell cushion.


This Ary Professional eyeshadow palette is another item (the item on its left is their Charming Rose dark purple brush set with a clear case!)

Since I’ve not personally been here, I have again scoured through tons of reviews to bring you a condensed and neutral version of all the reviews:

  1. The location is convenient.
  2. Reviews mention that the cafe space is too small.
  3. Some reviewers mention that it’s warm in the cafe and the air conditioner did not seem to be working.
  4. Most of the praise goes to the desserts, but little is mentioned about the food. The prices of food sounds quite reasonable :
    • dessert and drinks 60 – 90 baht
    • frappuccino 140 baht
    • savoury items 150 baht
  5. The prices of the clothing and trinkets are reasonable.
  6. Reviewers recommend that it is better to go on a weekday to avoid the weekend crowd.


Right, so there are not many reviews right now (only 100+) since the cafe is still fairly new, since it was opened in August 2017.

But I think it would definitely be a good novelty experience to go, especially if you are a mermaid fan.
