Discreetly located in the Hotel Le Crystal in the heart of downtown, our restaurant welcomes you in a contemporary Asian decor. Our gigantic Buddha and our stairs in tropical colors will certainly not leave you indifferent. In summer, discover our charming colorful terrace for a refreshing cocktail. Thai cuisine is considered the finest in Asia. Its original and delicate ingredients such as curry, mint, lemongrass, coriander, kaffir lime or even red basil, its fragrances and its colorful and spectacular presentations will make you travel. But beware, it is also very spicy and can represent a real challenge for the taste buds! Siam offers you the great classics such as pad thai and curries, presented in a contemporary way. Our grandiose and warm decor as well as our dedicated staff invite you to come and experience the tradition of sharing typical in Asia. The address to remember for your business lunches, special events or just a good meal.

Excellente expérience au resto Siam. La bouffe est vraiment délicieuse, surtout la table d'hôte (plats à partager pour deux) qui vaut vraiment le détour. Les desserts sont aussi très bons. La serveuse était incroyable : attentionnée, professionnelle & chaleureuse. Le service de valet est un gros plus, très pratique. Je recommande fortement!
This place had a wonderful atmosphere, great service, & honestly the best chicken green curry I've ever had. This menu item had two'chili pepper' ratings, I had a third chili pepper for some extra heat, amd I loved every bite. My daughter had the seafood Pad Ki Mao & thought it was amazing. & the mango sticky rice for dessert was just the icing on the cake so to speak!
Went last night in a large group in the private room for a very special occasion. Fred was fantastic, attentive & so much fun. Will be returning, thanks Fred!
The main course was excellent; however, while you have a choice between a salad or soup for the appetizer, the Tom Yum Kung does not taste authentic-it contains neither kaffir lime leaves nor lemongrass.
Ordered delivery. First time trying their food. The mango salad was good & spicy. Pad seew & beef curry were very(!) dull in flavors, very plain. Not a single vegetable in the curry- just two pieces of meat in coconut milk. Super pricy & in my opinion not worth it at all.
Nourriture très goûteuse & savoureuse, pas trop piquante! Une bonne introduction à la cuisine thaïlandaise. Ambiance chaleureuse parfaite pour passer une bonne soirée & discuter.
Really enjoyed the vibe of this place. The food was delicious. We started with the chicken satay then had the beef pad seew & sweet & sour chicken. Would definitely return & recommend.

Sat quickly on a Tuesday at noon with family of five (kids 11, 13, 16) after morning at Musee de Beaux Arts. Server solicitous & helpful with menu. Each appetizer & entree delicious: mango salad, vegetable soup & chicken dumplings were standouts, along with Panang Curry, Crispy Chicken & Pad Thai. Popular with business lunchers but our family enjoyed the more professional atmosphere without ubiquitous crayons, paper placemats or chicken tender menu options. Lava cake, creme brulee with cappuccino & Americano was sweet ending & we wobbled out happily.
My son & I came in Saturday night as part of his birthday celebration. Our server Dav went above & beyond (truly great service!) . He made my 6 year old feel like a true VIP. - great food amazing service! Genuinely this is a destination restaurant we purposely travel from out of province to visit. Thank you Dav & Siam for an excellent experience!
If I return (which I definitely will), it won't just be because of the amazingly delicious food. it'll be because of the exceptional service especially from our waitress Heidi.
We mentioned that we'll be celebrating our anniversary soon, & she truly went above & beyond. She congratulated us, shared some great local spots around Montreal to check out, & even surprised us with a complimentary cheesecake.
This was honestly one of the best dining experiences I've had in Montreal so far. You guys truly are the best
Nous avons découvert le Siam proche de notre hôtel. La cuisine du restaurant vraiment très bonne , les plats étaient délicieux & bien servi. La serveuse Anael était vraiment agréable. Le seul GROS point décevant dans le restaurant, trop bruyant, le niveau sonore avec beaucoup de monde est impressionnant & en plus ils ont rajouté la musique beaucoup trop forte . Dommage !
