Our selection brought together chocolate drinks, a mousse cake, a bee-topped cupcake and four pralines.
Chocolab Bangkok is the chocolate café on the ground floor of SO/ Bangkok, near Lumpini Park. We stopped here while exploring the city’s chocolate cafés and found a room built around cocoa, from the giant chocolate-drop sculpture overhead to the pralines in the counter. Our visit brought good hot chocolate, a mousse-filled cake and a few memorable fillings, along with some shortcomings that were less obvious from the display.
Is Chocolab Bangkok worth visiting?
Best for: Chocolate lovers looking for a café break near Lumpini Park, with handmade pralines, cake and hot chocolate.

Chocolab’s interior makes its subject clear before anything reaches the table. Deep chocolate colors run through the room, and an oversized drop hangs from the ceiling above the display. The smell of chocolate helps the theme along without any assistance from the décor. There is a playful side to the place, softened by leather seating and the daylight coming through the windows.
The chocolate laboratory is visible through glass, so the preparation area becomes part of the café. Whether you catch the chocolatiers at work depends on what is happening when you arrive. Despite the laboratory idea, the seating area is comfortable and informal, with a large floor lamp beside the chairs and windows along one side. It is an easy setting for taking your time over a drink and deciding which small temptation should come next.
The drinks selection gave us more choice than a straightforward cup of cocoa. Floats and frappés sat alongside iced teas, fruit-based drinks, coffee and a few celebratory options. Some combinations looked substantial enough to compete with dessert. We chose two chocolate drinks, a milky frappé and the Hot Chocolate Vienna, which turned out to be our preferred choice.
Our chocolate frappé was light and refreshing, a welcome quality in Bangkok’s heat. The Vienna brought a different pleasure: silky hot chocolate with good vanilla ice cream. As the ice cream melted, it cooled the drink a little and left a creamy foam on the surface. Both drinks were lighter than their chocolate-heavy surroundings might suggest, and the Vienna’s smooth texture was the reason we liked it most.
At Chocolab, it is worth looking around the display before choosing from the printed menu. Pralines, cakes, cupcakes and chocolate lollipops gave us a better sense of the selection than the list of staple items alone. At the time, the chocolate offering included 70% Bonnat chocolate, alongside the white and milk chocolate pieces we tasted. Salads and toasted sandwiches also appeared on the menu, though chocolate was the reason for our stop.
The So Royal cake put chocolate into every layer: a glossy topping, plenty of mousse and chocolate sponge, with a crisp waffle layer at the bottom. Poppy seeds added a small extra detail. What we enjoyed most was the generous mousse filling, which gave the slice a creamy center and made this the cake we would have chosen again from our order.
The cupcake arrived with a chocolate lattice and a little bee on top, an elaborate decoration for something eaten in a few bites. Inside, the honey filling brought moisture to the spongy cake. Its fragrance was stronger than we wanted, and we would have preferred a more natural honey flavor. The chocolate ganache was also dry, so the cupcake did not quite deliver on the promise of its appearance.
We tried four pralines and enjoyed them to different degrees. The white chocolate with coconut and lemongrass was the gentlest: the coconut was faint and the lemongrass almost disappeared. Honeycomb, another white chocolate piece named for its shape, held a milk chocolate ganache that we liked. The Five Elements Fire “Chili” praline lived up to its name, bringing a manageable warmth to melting dark chocolate.
Diamond Passion Fruit was our favorite. Its pronounced fruit flavor came through clearly and made the small piece disappear a little faster than we would have liked. Compared with the more restrained coconut and lemongrass filling, it gave us the clear flavor we were looking for in a praline.
The menu currently linked by SO/ Bangkok lists à la carte desserts at THB 125–350 and hot chocolate at THB 200–220, plus 10% service charge and 7% VAT. For a dessert and hot chocolate, allow about US$12–20 per person including those charges. This is a guide to the hotel’s linked June 2025 menu, checked in October 2026. The selection shown in our original review came to a little under US$30; that historical bill is separate from today’s price guide.
There are also bookable experiences beyond a café order. The current Chocolab HI-TEA offer is THB 790 net for two, approximately US$24, served daily from 1:00 p.m. to 5:00 p.m. The hotel describes it as a chocolate afternoon tea using Belgian couverture. Its online voucher requires a reservation one day ahead.
The chocolate-making class lasts 45 minutes, with a listed daily slot from 2:30 p.m. to 3:15 p.m. The online offer is THB 890 net per person, around US$26.50, for adults and children aged six and older. Classes take two to twelve participants and require at least 24 hours’ advance reservation, subject to availability. We have not tried either the current tea set or the class, so our rating remains an assessment of the café visit described above.
Chocolab is a good stop for chocolate lovers who want a comfortable café near Lumpini Park, with a working kitchen and plenty to choose from. We remember the vanilla ice cream melting into the hot chocolate, the So Royal cake’s mousse and the lively passion fruit filling. The breadth of the display was appealing, although a smaller selection with more consistent freshness would have made the experience stronger.
We would also have welcomed a choice of chocolate for the hot and iced drinks, with a few samples to help customers find their preference. That would make good use of the laboratory idea. Chocolab was one stop in our wider exploration of Bangkok’s chocolate cafés, where different places gave us different reasons to linger over cocoa. Here, we would start with the Vienna and choose the rest with a little care.
