Editor’s Note: Updated September 2026. This review describes our mangosteen-themed afternoon tea at Zest Bar & Terrace, originally published in 2018. The menu and price belonged to that seasonal promotion; current venue details have been checked separately.
Our Zest Bar & Terrace afternoon tea review began with a fruit we usually prefer to eat fresh and ended with mangosteen appearing in everything from smoked duck panini to cheesecake. Served inside The Westin Grande Sukhumvit in Bangkok, this seasonal set was playful, generously priced and far more thoughtful than its miniature picnic-table presentation first suggested.
The food was the reason to come. Savories made particularly clever use of mangosteen, the desserts kept the fruit recognizable, and the service was polished. The room itself looked tired even then, and the English Breakfast tea and scones did not quite match the standard of the bites. Here is how the full experience unfolded.
Was Zest Bar & Terrace afternoon tea worth booking?
What We Loved
- Creative use of mangosteen in both savory and sweet bites
- Excellent smoked duck panini and quinoa salad
- Playful picnic-table presentation

What Could Be Better

- The English Breakfast tea lacked depth
- The scone was floury and missed a crisp crust
Best for: Fruit lovers and curious afternoon tea guests who enjoy a strong seasonal theme carried through the entire set.

Mangosteen Afternoon Tea at Zest Bar & Terrace
Zest Bar & Terrace built this themed afternoon tea around mangosteen, using the fruit in every course without making the menu repetitive. Mangosteen is among our favorite tropical fruits, although peeling it is less charming than eating the snow-white segments inside. Here, the kitchen kindly did that work for us.
The kitchen treated mangosteen as more than a garnish. Its sweetness and acidity became part of the structure of each bite, sometimes fresh and sometimes cooked. That distinction mattered, because heating softened the fruit’s bright character and made it rounder and more comforting.
The miniature wooden picnic table added a casual note to dishes that had clearly required careful preparation. Beyond the glass, traffic moved constantly through the Asok intersection, giving this hotel lounge tea a distinctly urban backdrop.
Tea and Savories
The savory course was the strongest part of this Zest Bar & Terrace afternoon tea. We started with English Breakfast tea, which was gentle and mellow, though less robust than we expected. The food soon claimed our attention, beginning with a smoked duck breast panini and mangosteen compote.
The fruit brought juiciness and measured sweetness to the tender duck, and the panini was easy to eat without losing its filling. An avocado and mangosteen bruschetta followed. The combination recalled guacamole, with the fruit adding a bright sweet-and-sour note that worked surprisingly well.
The most memorable savory was the herb-flavored quinoa and mangosteen salad. The kitchen had made a small bread shell that resembled a mangosteen rind in size, shape and deep reddish-purple color. It was not merely decorative. The bread softened the shallot and tomato seasoning, while mangosteen supplied the sweet acidity that tied the salad together.
Before moving to the desserts, we tried the mixed berry scone with mangosteen jam. The jam was concentrated and full of fruit, to the point that it overshadowed the scone. We missed a crisp outer crust, while the crumb was too floury. Even so, we would happily have taken another spoonful of the jam.
Mangosteen Sweets
The dessert course kept mangosteen recognizable while pairing it with familiar pastry flavors. Rather than relying on decoration alone, the kitchen used the fruit’s acidity to balance yogurt, vanilla, sponge and cream cheese.
Clafoutis, Panna Cotta and Cheesecake
A tropical interpretation of French clafoutis showed how naturally mangosteen could move into a European-style dessert. The mangosteen yogurt panna cotta with vanilla bean was equally successful: vanilla softened the yogurt’s tang, while the fruit topping restored freshness.
A layered mangosteen compote and vanilla sponge arrived in a small blue bowl. The sponge was soft enough to combine easily with the fruit, berries and cinnamon seasoning, producing one of the most balanced desserts in the set.
The final dessert was a mangosteen cheesecake. Rich cream cheese suited the softer character of baked mangosteen inside the cake, and fresh fruit on top supplied the livelier contrast we had come to enjoy throughout the afternoon.
Conclusion: Was Zest Bar & Terrace Afternoon Tea Worth It?
This mangosteen afternoon tea was worth booking for its food, imagination and excellent value. The savory course was particularly convincing, and the desserts showed several sides of the same fruit without simply repeating one flavor. The tea and scone were weaker, though neither spoiled the experience.

Our reservation came with one clear qualification: the interior looked worn beside Bangkok’s increasingly polished afternoon tea rooms. The plants helped, as did the view toward Asok, yet the setting did not reach the standard of the kitchen.
