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.
Ma copine & moi sommes allés chez Siam pour la Saint-Valentin, & n'avons pas été déçus! La qualité des entrées & du repas principal étaient excellentes, en plus d'un service impeccable & d'une rapidité notable. Le seul petit bémol était le dessert spécial, préparé pour la Saint-Valentin, qui était un peu trop petit & décevant comparativement au reste du repas. Nous avons déjà hâte à notre prochaine visite!
Again, Siam does not disappoint!
Hubby & I had our Valentine's supper there. The place was busy but it did not feel hectic. The food was amazing, as always.
The server was great & their house cocktail was extraordinary!
Cannot wait to come back.

We were 4 people on February 13. There was a valentines menu, which had great choices & 99 $ per couple.we all took that & it was really great! We were sharing everything, so we get to taste everything on the menu! The food was full of flavors, very fresh! The service was truly impressive! We are all in awe ! Amazing place , I totally recommend it!
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.
Resto vraiment agréable, un passage obligé downtown ! Service de grande qualité & que dire des plats servis ! Nous avons commandé 3 plats différents & tous étaient savoureux, bien dosés & joliment servis. La serveuse était extrêmement attentionnée & les accessoires (baguettes, verre d'eau) sont proposés avec grande délicatesse. Je recommande pour dîners d'affaire, discrétion & confort seront présents sans aucun doute !

Après avoir goûté aux cocktails, à l'assiette dégustations pour 3 personnes (5 dégustations différentes), aux mets principaux & desserts, il n'y a absolument rien que je peux prétendre ne pas avoir aimé.
De plus le serveur était des plus sympathique &, de toute évidence, savait qu'il nous proposait un menu exceptionnel. En sortant du Siam, tout le groupe était rassasié.
L'endroit était très charmant avec un éclairage tamisé intime. Nous avons constaté qu'il y avait un grand nombre de face-à-face romantiques & je crois, aussi, que c'est un un lieu parfait pour une première rencontre
I love the vibe of the restaurant, the service, & the quality of the food vs price, totally worth it. I will come back (we were celebrating a birthday & the cheesecake the restaurant have us was amazing 🎈❤?).
Je suis allée manger chez Siam centre-ville pour le lunch avec un collègue & j'ai passé un très bon moment. Le service était rapide, la nourriture bien goûteuse & les portions généreuses. Les plats étaient vraiment bien garnis & savoureux.
Seul petit bémol, il y avait pas mal de bruit, ce qui rend la discussion un peu moins facile à l'heure du midi.
Pour le prix, c'est un très bon restaurant & j'y retournerais sans hésiter.
Excellent night out. Super great atmosphere on a sat night. Music was great. The food was great. Service was excellent 💪🏾My wife & I are in total agreement this is our fave restaurant. & YES try the wings in entrée amazing 👏🏽

Went here with my partner. Upon entering, we were coldly asked if we had a reservation, to which I replied no. The guy walked closer & stared at my partner for a solid 5 seconds before looking at another server & asking him to find us a seat. After being seated, we got a new server who brought us the menus. There was a large gap in time from when we received the menus to when the server actually took our order. Server was just walking around making conversation to other servers/customers while we waited to wave him down. While explaining a few dishes to'us', he never once looked in the way of my partner, nor addressed her to ask her if she needed anything. He only asked questions to me, only looked in my direction. When my partner pointed at the menu to inquire about a dish he was very dismissive. The atmosphere is nice, lighting is warm & dim & the interior design is intentional. The food was flavorful & well balanced, but the service left a sour taste in my mouth.
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
Stunning! Fresh, bright flavors in all the food items I had.
✅The tom yum soup, while lighter on coconut milk than I am accustomed to, & sans mushrooms, was chock fill of lemongrass, lime, & just the right amount of chili flake.
✅The pad mee was so lovely with its vegetables crisp, vermicelli noodles with perfect bite, & a generous portion of chicken. I, in fact, could not finish the portion on my own.
✅I finished with the sorbet & found them delicious without being overly sweet.
Would absolutely return to Siam, & would recommend it to anyone.
