Siam is a consistently impressive Thai dining spot in downtown Montreal where vibrant, well balanced flavors meet generous portions, a stylish yet inviting ambiance, and attentive service. Reviewers praise the wide menu from green curry to pad Thai, dumplings and satay, noting fresh ingredients, colorful presentations and many vegan options. The service is repeatedly described as friendly, professional and helpful, with staff guiding choices and making celebrations feel special, while the terrace and warm lighting add to business meals and gatherings. While busier evenings can bring noise and occasional slower pacing, the overall experience is high quality, good value for the portions, and a welcoming atmosphere that invites return visits. The result is a top choice for Thai cuisine in the city, where guests leave looking forward to the next visit.
We went to Siam hoping to experience the MTL À table menu, however, when we were seated we were told that because there was a hockey game that evening, the service for the table d'hote would not start until 7p. Had I known this, I likely would have booked a later reservation but there was no mention of this at the time of booking.
We arrived slightly early & we were seated at the bar for a drink before our table became available, which was nice to just take in the ambiance & enjoy a beverage. Once seated we decided on some dishes & they were quite delicious, 10/10 across the board. Our server was also quite pleasant & checked in on us a few times throughout our meal.
The disappointing part was that it felt as though we were being rushed out. We barely sat for an hour & our meal was wrapped up. Additionally, we asked for the bill at the end, however, we still had 1/2 of our cocktails left & had intended to sit & enjoy them. When we were first seated we were told the next reservation for that table was 8:15pm & it was only 7:25pm so we figured we could chat & enjoy our drinks. However, our server promptly came over after we paid & said that the next guests arrived early (by an hour??) & that she was hoping we could clear our table within 5-10 minutes & that we could move to the bar if we really wanted to stay. Honestly, this put a damper on our experience for two reasons: (1) it felt like because we were potentially not going to spend more money that night we needed to leave & (2) we were early ourselves & sat at the bar, so why could the second set of guests who were an hour early not do the same?
All in all, our food was great but the night ended a bit sour for us with the service.

Came with a colleague for dinner on Monday around 8:30 pm. The dining room was gorgeous but despite having a reservation we were unfortunately sat in a hidden corner tucked behind the bar with awful bright lighting & no view. We then were never greeted by a server, in fact we waited almost 25 minutes & had to flag down the hostess to ask for service. She sent someone who hurriedly & extremely casually greeted us but then told us he had to bus a table before he could take our order, it was a very awkward interaction, it felt like we were inconveniencing someone who was clearly too overwhelmed to take care of us. He never gave us even a glass of water throughout our entire dinner despite us asking for it multiple times. We finally were able to order, but it honestly felt like having my order taken at Wendy's, the experience was far too casual & rushed. The food runner who brought our dishes was more professional than the waiter. Despite the waiter acknowledging how long we had waited, we were not offered anything nor did a manager come to see us.
The food, I must say, was fantastic. It was almost worth the abysmal service. The salmon in yellow curry was gorgeous & delicious. I think next time I'll just get take out & eat at home. Bad service seems to be more common throughout the city these days, it's a shame that guest experience & high standards of service are so low on the list of priorities for many restaurants in Montreal, especially downtown.
Lors de l'événement Montréal à table, mes amies & moi choisi le Siam. Nous avons apprécié l'excellent service de Julien. Bouffe superbe, tout était délicieux . Atmosphère agréable quoique la musique était un peu forte. Merci Julien de nous avoir chouchouter.

Amazing ambience at the restaurant with great food quality. I was surprised to find yummy vegan options here. Love their Mango Sorbet. Definitely a hidden gem in downtown.
I had a really great time at Siam. The food was really delicious, we ordered 3 different ones & shared, I can assure you they were all tasty. Fredrick was also quite nice, & he made the night more enjoyable for us with his presence & service. If you like spicy food, don't be afraid of Cashew Chicken.
The last time I was in this location was many years ago for a work related function. This time it was for pleasure with former work colleagues. The food was great. The place was really noisy (game night & a private party close to where we were seated). Service was good at the beginning & then kinda dropped off. The server never came back to fill the waters. When we asked for knives to cut up spring rolls for sharing she only brought 1 knife. We were a party of 3. All in all a good experience, but always a bit of room for improvement!

Superbe découverte ! Le repas était savoureux, les assiettes bien garnies & le service attentionné & sympathique. Une belle expérience du début à la fin - j'y retournerai avec grand plaisir !
Wow, I just had the best Thai food ever! Seriously, the flavors were incredible & everything tasted so fresh. Our server was amazing, he was super friendly & attentive. Olivier definitely made the experience even better! I'm already planning my next visit!
Je suis allé avec ma famille pour un bon souper au restaurant avant la partie des Canadiens, & ce fut excellent! Notre serveuse, Julie-Anne, était incroyable! Un service formidable de sa part. De plus, le manager Hassan nous a bien accueilli & est super sympathique! La nourriture était très bonne. Toute une belle soirée passé au Siam, en belle compagnie

Nous étions allées en Thaïlande il y quelques années & nous adorons nous remémorer l'expérience... Ce fût une réussite!
Nous avons suivi les recommandations, un vrai délice nostalgique.
Le serveur était adorable, charmant. Je cherche à prendre contact avec lui 🫶🏻
Un Frédéric!?... Centre-Ville de Montréal.... 🫠
Belle expérience cette semaine au Siam du Centre-Ville.
L'atmosphère légèrement tamisée de la salle du bas était très agréable.
J'ai apprécié qu'on m'ait accommodée pour m'asseoir à notre table un peu plus tôt. Nous avions une réservation pour 18h15 le mercredi mais quand je suis arrivée à 17:50, notre table était déjà prête & notre serveur Davinder a pu m'y asseoir.
Niveau menu, on retrouve pas mal de classiques Thaï avec de belles options vegan également. J'avais opté pour les excellents dumpling au poulet sauce arachide & le pad Thaï au poulet dont la portion était bien généreuse (la photo ne lui rend pas justice). Attention juste, le menu ne l'indique pas mais j'ai trouvé la sauce des dumplings légèrement épicée. Je ne la recommanderai pas pour des personnes sensibles aux épices ou des enfants. Ça vaudrait peut-être un piment ou 1/2 piment sur le menu.
Mention spéciale pour le mango sticky rice cocktail, doux & délicieusement fruité.
En dessert nous avons opté pour un classique moelleux au chocolat avec sorbet coco. Rien d'exceptionnel mais c'était tout de même très correct.
Gros bonus pour le service exceptionnel de notre serveur Davinder qui a été souriant & aux petits soins du début à la fin. Il a vraiment égayé notre soirée & contribué à rendre notre expérience mémorable.
Nous venions initialement pour la bouffe & le décor mais nous reviendrons très certainement pour la qualité du service & belle atmosphère du lieu.
