Siam Thai

What Siam Thai does

Siam Thai is a single-location Thai restaurant operating at Bahnhofstrasse 16 in the Bülach shopping district of Switzerland, since April 2022. The business is conducted through the legal entity Aroi Gastro AG, registered at Feldstrasse 14, Bülach, and is independently owned with no disclosed external investors. The kitchen is led by Chef Chayabut working with his partner and two brothers, with Wichuda and Wetisa managing front-of-house service — an in-family team that is the core of the restaurant's authenticity proposition.

The restaurant's core offering is authentic Thai cuisine presented with only minor adaptations to Swiss preferences (reduced default chili and coriander levels, with original Thai spice levels available on request). Three service channels form the revenue base: dine-in service at the restaurant, take-away ordering through a dedicated webshop (webshop.siamthai.ch) that offers a 2 CHF discount on main dishes for pickup, and an in-house home/office delivery service. Two buffet formats supplement the à la carte menu: a weekday lunch buffet (Monday-Friday, 5 dishes plus appetizers at 17.50 CHF per portion for take-away) and an all-you-can-eat in-restaurant buffet (22.50 CHF for adults, 12 CHF for children up to 12 years). Pricing across the menu is unit-based and pay-as-you-go, with sample à la carte mains around 24.50 CHF (e.g., Som Tam Thai with shrimp).

From a go-to-market and technology standpoint, Siam Thai is a direct-to-consumer, walk-in-driven local restaurant. The technology footprint is minimal: a WordPress-based public website with a linked take-away webshop, third-party reservations via Foratable, and a coffee partnership with Henauer. The restaurant has no mobile app, no API, no disclosed integrations, and no proprietary technology. Marketing relies on the prime pedestrian location near Bülach train station, walk-in foot traffic from the shopping district, word-of-mouth, and the Swiss Guest Award recognition from Lunchgate in both 2023 and 2024. Operating hours are six days a week (closed Tuesdays), with extended dinner service on weekends.
