The Old Siam Plaza

4.2(12,242 reviews)

Tucked along Tri Phet Road in Bangkok's historic Phra Nakhon district, this multi-storey shopping plaza offers a quieter, more traditional alternative to the city's modern malls. Sitting comfortably within the old town, it draws visitors who want a glimpse of classic Bangkok commercial life rather than the polished uniformity of larger retail centres. The plaza is particularly well regarded for its silk and traditional Thai clothing, with upper floors home to numerous shops selling formal wear, event attire, and intricately crafted garments — especially for women. Jewellery stores are well represented throughout the complex, and the ground level and surrounding area offer street food and light snacks alongside a food mart for everyday essentials. The atmosphere feels organised and unhurried, and the strong air conditioning throughout the building makes it a practical and welcome retreat during Bangkok's hotter months. Good to know: The plaza sits a short walk from the Pak Khlong Talat flower market, making it straightforward to combine both into a single outing. Smaller vendors may prefer cash, so carrying Thai baht is advisable. Comfortable footwear is recommended for those planning to browse across multiple floors.

Visitor Reviews

The Old Siam Plaza is a charming and nostalgic stop in Bangkok’s historic old town — a welcome contrast to the big modern malls elsewhere in the city. It feels like a window into classic Bangkok, with traditional architecture, a relaxed vibe, and a mix of interesting shops and food stalls. I especially enjoyed wandering through the ground floor food area with Thai snacks and sweets, and checking out the variety of silks, fabrics, and local boutiques upstairs. It’s a great place to pick up unique Thai textiles or just take a break from the heat in the air-conditioned interior.

Old Siam Mall is such a nice and tidy place to explore! The mall is clean, organized, and full of shops selling beautiful silk dresses and traditional Thai clothes, some even have good promotions. You can also find lots of local snacks here, all looking clean and hygienic, with fair prices. The top floor has a food court with a few halal options too, which is great for Muslim visitors. It’s a good spot to experience local Thai culture, shop for quality fabrics, and grab some snacks in a relaxed setting.

This place is silk heaven with many shops on the upper floors catering excellent events wear, particularly for women. The clothes are simply exquisite. There’s also a food mart and some jewellery stores. It’s not as busy as the larger malls but I like it for that reason.

Tips for Visiting Markets & Shopping

Haggle at Markets, Not Malls

Prices at market stalls are negotiable — start at 50–60% of the asking price and meet in the middle. Fixed-price shops and malls don't haggle. Smile and keep it friendly; aggressive bargaining is considered rude.

Arrive Early or Late

Vendors believe the first sale of the day is lucky — you'll often get a better deal if you arrive right when the market opens. Late in the evening, sellers may also discount to avoid packing unsold goods.

Be Cautious with Tailors

Bangkok has excellent tailors, but also many tourist traps. Avoid anyone offering suspiciously cheap suits or who approaches you on the street. Ask your hotel for recommendations, read reviews, and always get two fittings.
