We arrived at Siam Square One to explore the mall, and it turned out to be quite different from the others we’ve visited. It’s designed as an open style mall, giving it a lively and refreshing vibe, but once you step inside each store, it’s comfortably cold and cozy. The mix of open air walkways and airconditioned shops makes it a unique and enjoyable place to visit. A nice spot to stroll, shop, and cool off at the same time! 😄🏙️🛒

Siam Square One is truly fascinating – ultra-modern design with giant LED screens that immediately catch your eye. The mall is directly connected to BTS Siam, which makes it super convenient. It’s not only a shopping mall but also a link to the lively Siam Square area, especially Soi 7, with plenty of shops, cafés, and street vibes. A must-see spot if you want to experience Bangkok’s modern side right next to its trendy street culture.

Another great shopping center that’s connected to many other centers through the BTS walkway, super convenient. Clean with many great stores and restaurants. Has bargain stores along with your traditional name brand retail stores.

This mall has no air conditioning and is designed as an open-air mall, but with Bangkok's weather, shopping in the mall becomes somewhat of an ordeal unless you quickly run yourself into the shops. Several of the shops here are selling cosmetics and beauty products and seem to be mainly catered towards young ladies. Definitely not one of my favourite malls in Bangkok or Thailand.

Siam Mall is an absolute must-visit in Bangkok! The variety of shops, from high-end brands to local boutiques, is incredible, catering to every budget and style. The mall is modern, clean, and well-organized, making the shopping experience enjoyable and hassle-free. There are also plenty of dining options, offering everything from authentic Thai cuisine to international favorites. What really sets it apart are the special events they host – I had the chance to attend the J-Show last weekend, and it was amazing! The performances and energy brought such a unique and exciting vibe to the mall. Whether you're shopping, dining, or enjoying one of their fantastic events, Siam Mall truly has something for everyone!

A fun place to shop, eat and people watch, as well as listen to lots of free musical events and see unexpected events (like a Greek yogurt parade!). Always crowded, always a bit of fun.

Alternative mall from MBK and Siam Paragon. A bit quiet but convenient

The mall has an interesting design in that several parts of the roof are open. I can appreciate that letting in some natural light is a good thing. However, I visited in October when there was heavy rain. Several parts of the mall were flooded and there was an army of cleaners attempting to clear the water.
