If you’ve ever wandered through a Bangkok night market and caught the aroma of caramelized sugar and freshly fried crepes, you’ve likely stumbled upon Thailand’s sweetest street food secret — Roti Sai Mai.
This colorful dessert, often called Thai cotton candy, combines a whisper-thin roti (crepe) with silky threads of spun sugar that melt on your tongue. Originally from Ayutthaya, it’s now a must-try treat in the capital — but only if you know where to find it.
In this insider guide, you’ll discover exactly where to buy Roti Sai Mai in Bangkok, from legendary roadside vendors to hidden dessert stalls tucked inside bustling markets. I’ll also share local tips on when to go, what to order, and how to spot the freshest batches — just like a Bangkok native would.
🍬 What Is Roti Sai Mai? A Sweet Bangkok Story
Before you chase down your first bite, it helps to know what makes this dessert so special.
Roti Sai Mai literally means roti with silk threads. It’s made by stretching sugar syrup into delicate, hair-like strands — similar to cotton candy — and wrapping them in a soft, chewy roti. Each bite delivers a blend of nutty, buttery, and sweet flavors, often tinted with pastel pinks, greens, and yellows.
In Ayutthaya, families have perfected the craft for generations. In Bangkok, these artisans often sell their creations at weekend markets, temple fairs, and along busy roads like Phahonyothin, Chatuchak, and Victory Monument.
💡 Local Tip: The thinner the roti and the fluffier the sugar strands, the better the Roti Sai Mai. A true Bangkok sweet tooth can spot quality from a distance!
🛵 Route 1: Roti Sai Mai Mae Pom — The Legendary Stall at Chatuchak Market
If you’re serious about finding authentic Roti Sai Mai, Mae Pom at Chatuchak Weekend Market is your first stop.
- 📍 Location: Section 25, Soi 2, Chatuchak Weekend Market
- 🕓 Hours: Fri–Sun, 10:00 a.m. – 6:00 p.m.
- 💴 Price: 20–30 THB per pack
Here, you’ll see Roti Sai Mai being made right before your eyes — dough spinning, sugar stretching, steam rising. Mae Pom’s version is famous for its paper-thin wraps and lightly toasted edges that add a satisfying crunch.
🥢 Traveler’s Note: Arrive before noon. By afternoon, the line of locals (and curious tourists) winds around the corner.
🌈 Route 2: Roti Sai Mai Pa Aree — Victory Monument’s Late-Night Favorite
When the city quiets down, Victory Monument comes alive with night vendors — and among them stands Pa Aree, known for her rainbow-colored Roti Sai Mai.
- 📍 Location: Ratchawithi Road, near Century Mall
- 🕘 Hours: 5:00 p.m. – 11:00 p.m. (Daily)
- 💴 Price: 25–35 THB
Her bright pink and green roti wraps are as Instagram-worthy as they are delicious. Locals swear by her generous portions of Sai Mai — soft, fragrant, and never cloying.
💬 Insider Tip: Ask for the “double wrap” — two layers of roti filled with extra strands. It’s a local secret for a more satisfying bite.
🌸 Route 3: Ayutthaya Roti Sai Mai Original at Or Tor Kor Market
For those who want the Ayutthaya original without leaving Bangkok, head to Or Tor Kor Market, one of the cleanest and most gourmet markets in Thailand.
- 📍 Location: Opposite Chatuchak Park MRT Station
- 🕒 Hours: 8:00 a.m. – 6:00 p.m. (Daily)
- 💴 Price: 40–50 THB
This stall sources directly from Ayutthaya every morning, ensuring freshness and authenticity. Their roti is elastic and slightly buttery — perfect for balancing the sweet threads.
🧡 Local Tip: Pair it with Thai iced tea for the ultimate afternoon snack.
🌇 Route 4: Roti Sai Mai at Talad Neon Night Market
If you love a more modern, photogenic vibe, Talad Neon Night Market on Phetchaburi Road offers a fun take on traditional desserts.
- 📍 Location: Phetchaburi Soi 29-31 (near Pratunam)
- 🕖 Hours: 4:00 p.m. – Midnight

🍡 Route 5: Roti Sai Mai at Train Night Market Ratchada
Before its renovation, Train Night Market Ratchada was one of the city’s best late-night dessert hubs. Now, many vendors have moved to nearby JODD FAIRS, bringing the same charm (and sweetness) with them.

- 🕘 Hours: 4:00 p.m. – Midnight
- 💴 Price: 25–40 THB
Look for stalls labeled “Roti Sai Mai Ayutthaya.” You’ll often see families making it together — one spinning dough, another stretching sugar, and kids rolling it up with practiced hands.
💡 Bangkok Vacay Tip: Buy a few packs to share — they taste best fresh but travel well for a few hours.
🌿 Route 6: Roti Sai Mai at Wang Lang Market (Riverside Gem)
Across the Chao Phraya River near Siriraj Hospital, Wang Lang Market is a paradise for old-school Thai snacks, and Roti Sai Mai is one of its best-kept secrets.
- 📍 Location: Wang Lang Market, opposite Tha Chang Pier
- 🕑 Hours: 10:00 a.m. – 5:00 p.m.
- 💴 Price: 25–35 THB
The Roti Sai Mai here tends to be less sweet, favored by older Thais who appreciate subtle flavor. Expect a slightly thicker roti — chewy, warm, and aromatic.
🌾 Local Favorite: Pair it with grilled bananas or pandan custard from the next stall over for a full Thai street dessert experience.
🏮 Route 7: Floating Market Finds (Taling Chan & Khlong Lat Mayom)
For something more traditional, hop over to Bangkok’s weekend floating markets. Vendors often paddle up with baskets full of sweets, including Roti Sai Mai wrapped in banana leaves.

- 📍 Khlong Lat Mayom: Near Bang Khun Non
- 🕒 Hours: Sat–Sun, 8:00 a.m. – 4:00 p.m.
- 💴 Price: 20–30 THB
The experience is as sweet as the treat — exchanging coins, receiving a warm packet of Roti Sai Mai straight from a wooden boat.
🌺 Pro Tip: Go early. The floating markets get crowded by 10 a.m., and the dessert sells out fast.
