Nous sommes allé un vendredi soir au Siam & nous sommes tombés en amour avec la place! À commencer par une accueil chaleureuse de Claude dans ce merveilleux décor Thai, nous avons essayé leurs cocktails signatures, puis mangé du cari au boeuf ainsi qu'un sauté de légume au poulet & gingembre. C'était un véritable régal. Que de plaisirs, je recommande fortement!
Very accommodating to our friends gluten sensitivity. The waitress took her order & went through each item with her. Great service.
Good was delicious especially the pad Thai.
Tom yum soup was spicy & delicious just wish the bowl was bigger. Overall great experience. Book reservations for dinner, otherwise you may not get in.

I'm visiting from Calgary & had the pleasure of dining at Siam here in Montreal where Fred was our server. I can confidently say he is absolutely phenomenal at his job.
From the moment we were seated, Fred was attentive, friendly, & incredibly knowledgeable. He made thoughtful recommendations, checked in at just the right moments, & made us feel genuinely welcome throughout the entire meal. His professionalism combined with a warm, positive attitude truly elevated our dining experience.
It's clear that Fred takes great pride in what he does, & it shows in every interaction. Service like his makes a lasting impression & turns a great meal into a memorable one.
If you're dining at Siam Thai, you're in excellent hands with Fred. He's a true asset to the restaurant, & I wouldn't hesitate to recommend this place to anyone visiting or living in the area.
Visited during weekday lunch. Great food - the authentic flavors were there. Friendly staff service. Pricing wise - in the expensive side for a Thai restaurant. Perhaps because of the location. Ordered these 2 & water for about $63.
Nice service, dinner & dessert choice. Tried the duck dumplings, yellow curry & shrimp pad Thai. Service on Mar 7 was disappointing as we felt neglected as waiter did not even ask us how our meal was & we had to ask for water to be refilled from person that was bringing out the food. We spoke to hostess & she offered free dessert but we declined. Food was fine.
L'affaire qui m'a le plus déçu, c'est qu'il y avait une promotion sur le vin (lundi & mardi) à 50 %, mais c'est quand j'ai reçu ma facture que j'ai su que ma bouteille n'était pas applicable.
Pour la nourriture, nous nous avons pris un pad thaï aux crevettes. Seul commentaire, car c'est non décortiqué, c'est moins fun!
Le serveur était super gentil, lorsque présent.

Siam is an excellent Thai restaurant downtown.
I've been there three times, including Valentine's Day with friends, & the experience has always been great.
Delicious food, very good service, & a warm, lively atmosphere.
Consistently enjoyable... well deserved 5 stars.
Always enjoy SIAM - the food ( especially the Pad Thai & professional service. Chloe even remembered me even though it had been awhile since my last visit. It's an added touch that really makes a person feel welcome.
Also appreciate that they have zero Sapporo beer.
Will be back over the holidays.

Great food. Mango salad was refreshing. The pad Thai was oily it's sweet than what I've had in Thailand. Could have had more tofu & less veggies. Definitely recommend for Thai food
Had a pleasant experience at this Thai restaurant in Montreal!
I went with a few friends for dinner at Siam for dinner. I ordered the green curry with braised beef & a chocolate lava cake for dessert. The braised beef was tender & flavorful. The green curry was not overly spicy, just perfect for my spice tolerance. The chocolate lava cake was enjoyable too, liked the scoop of ice cream on top.
The decor & ambiance was quite nice. I like the dimmer lighting & it wasn't not overly loud inside the restaurant.
Service was really good! Our waiter Frederique was very welcoming & walked us through the menu at the start as it was our first time at the restaurant. Always dropped by & checked on how the food was. There was also someone in a white collared shirt walking around all the tables checking on how the dinner experience was going, I appreciated that, I think he might've been the manager.
Food came out in a reasonable time considering we were a party of 6 people.
The food was just sophomores goooodd!!!Will definitely be back for more! The krapow & pad Thai were just outstanding. The cocktails were well made too.

Don't get fooled by the name, it's a bar & lounge, not quite a Thai restaurant. It's what they call a fine dining experience. There's an indoor entrance from the hotel Warwick Le Crystal, so reservations are expected-- especially at night when it can get really packed. Has a nice atmosphere if you're looking for fancy places. I usually go there for the dessert only, they have a truly nice crème brûlée.
Plus d'une heure d'attente pour un pad Thai eg un riz crevettes ! La serveuse nous annonce au bout de 45min qu'un groupe de 60 personnes est la & donc la cuisine est garanti. Dans ce cas il faut prévenir le client ou bien fermer les réservations car la cuisine est débordée. Ni l'un ni l'autre n'a été fait… la nourriture arrive, le pad Thai était sucré comme une gaufre liégeoise, très très déçu ! C'était ma 3eme fois dans ce reatau, ça sera la dernière!!!
Amazing service & wonderful people. The staff were incredibly friendly & welcoming & the food was outstanding. I recommend the Pad Kee Mao. Easily the best Thai food I've had. Highlyyy recommend
If your looking for an amazing Thai place in Montreal, I'd definitely recommend Siam! I sat at the bar with my friend where I was served by the bartender. They were very friendly! We got the Kai Yang chicken & the green curry with braised beef, & from the first bite all I could say is WOW! Excellent choice for a cute date night or even for celebrations of any kind! I'll be coming back😄
