The entry tier gets you in the door, but the 599-baht package is where the oysters and premium cuts live. Book the earliest slot you can stomach if you want to pace properly, because 90 minutes is tighter than it sounds once the first round hits the table. The location makes it an easy post-shopping stop, but treat the time cap as a hard line.

You step off the escalator on Siam Square One's fifth floor and the hot pot setup is visible through the glass before you reach the door. Each table has an induction burner and a split pot, and the meat trays start arriving within minutes of you sitting down.

The buffet runs on three price points. The 299-baht tier covers pork, chicken, and vegetables. The 399-baht middle tier adds seafood. The 599-baht platinum package brings Australian beef and oysters into the rotation. All three include the same time window: between 90 minutes and 105 minutes depending on when you check in, measured from the moment you sit.

The kitchen sends out Australian beef sliced thin enough to cook in seconds, shrimp that curl fast in the broth, and oysters that some tables order twice in the first half-hour. Vegetables, noodles, and Korean banchan sides sit at a central station. The staff circulate quickly, particularly when tables near the end of their session start to clear.

The restaurant operates within Siam Square One's daily schedule, which means 11 AM to 10 PM on weekdays and 10 AM to 10 PM on weekends. The fifth-floor location puts you one escalator ride above the main Siam BTS concourse, so the walk from the station turnstile to your table takes under five minutes. Reservations go through the phone line at +66 91 698 8570. Walk-ins work if you arrive outside the 12 PM to 2 PM and 6 PM to 8 PM windows, but the floor fills during those hours.

Order the premium tier if you came for the beef and oysters, not the base package. The 90-minute limit is firm, so start with the items that take longest to cook and work backwards from there.
