Was there to meet an old friend over dinner. I really loved the ambiance. The food, while it had great presentation, lacked any oomph to the flavor. The service seemed a little lacking but okay overall.
The food was absolutely delicious & beautifully presented. The ambiance was warm & inviting, perfect for a relaxing meal. Staff were attentive & friendly-definitely a place I'd come back to!
This was some of the best Thai food we've had in North America, & we say these as South-East Asians who've had a lot of authentic Thai food both in Thailand & back home in the region. The tastes were extraordinary & while not perfectly authentic, the chefs have done their own localization which makes the dishes extra tasty. Our only lowlight was the tom yum soup, which we felt missed the spiciness & we would have preferred if there was an option to have made it real Thai-spicy! We also had on a separate occasion from our dinner do a shrimp pad-thai room service, & that was excellent as well!
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.
