Reviews for Anantara Siam Bangkok Hotel
All class at the Anantara Siam.
If you are looking for a hotel in a great location that offers great value and genuine warmth through its people and service, then look no further than the Anantara Siam.

Thai Luxury in the Heart of Bangkok
The Anantara Siam has everything you need, especially for a family holiday. You can certainly leave the hotel and go anywhere in Bangkok you want. But why? You have beautiful rooms, a great pool with a reasonably priced bar attached, a good family room loaded with toys and attendants who can watch your kids, and a never ending breakfast where anything you can desire is served (personally, I love the endless bacon). Anantara has an approachable luxury and local charm that few other hotel chains can achieve. It isn't a Marriott nor a Hyatt, but it has a Thai 'flavor' that lends itself to lazy holidays, whether it's a couple's retreat or a family getaway. Can't recommend the Siam enough.

Nice
The restaurant offers a cozy and inviting atmosphere, perfect for a relaxing meal. The food was not only beautifully presented but also full of flavor. What made the experience truly special was the exceptional service from the staff—Mameaw, Lisa, and Anna were incredibly friendly, attentive, and went out of their way to ensure everything was perfect. Their warm hospitality added a personal touch that made us feel genuinely welcomed. Highly recommended for anyone looking for great food and even better service!

Biscotti
Had a lovely meal at Biscotti! The food was absolutely delicious — especially the sea bass and the Risotto Al Tartufo, both were outstanding. Big thanks to Khun Ma Miew, Lisa, and Anna for the amazing, warm service. Highly recommend — I’ll definitely be coming back!
