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!
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.

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.
Fantastic Thai restaurant in the middle of downtown Montreal. They have a wide variety of menu items, including your staple Thai cuisine such as pad thai, mango salad, tom yum soup, thai curry, etc. They also have unique options like a shared platter appetizers that let you try a bunch of different foods. Their cocktail menu is also quite unique, including a delicious mango based drink (available as a mocktail too).
Went for Friday night dinner & really enjoyed it! Delicious curries & yummy flavours. Lots of beef in the beef massaman curry & the duck leg was delicious as well.
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.
a strategic stop before a comedy show at the Bell Centre. Downtown, arena-adjacent dining can sometimes be… let's call it'efficient rather than exceptional.' Our expectations were... guarded.
We were wrong.
From the first bite of the Drunken Noodles, we realized this was no pre-show compromise. The spice level had just enough swagger to wake up the palate without sending us into a panic-induced milk-chugging spiral. The vegetables were beautifully cooked - vibrant, crisp-tender - & the noodles were deeply savory & generous. When I say generous, I mean the portion could reasonably feed two hungry adults, & still leave you negotiating a few final bites. We tried. We failed.
The green curry was equally rich, fragrant, & comforting.
The Mango Sticky Rice cocktail nearly stole the entire evening. Sweet, tropical, & indulgent. It was dessert & drink all at once.
For a downtown location, steps from the arena, the pricing felt almost suspiciously reasonable. Two hearty mains, a standout cocktail, & we walked out very full & comfortably under $100 for two people.
What began as a convenient pit stop turned into a genuinely memorable meal - the perfect (& unexpectedly delicious) opening act to our night.
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.
Overall, I recommend Siam restaurant!

Favourite restaurant in Montreal. This place NEVER disappoints. I went here for my birthday & the experience was perfect. The waiter was lovely, the food was absolutely delicious & they gave me a complimentary cheesecake with a sparkler in it which was special. The green curry was amazing but my favourite is the beef pad see ew. The mocktails are great too.
The Table D'hote was delicious! The appetizer platter was so tasty & a real variety. Our crispy chicken & beef curry were amazing. Our server was wonderful. She was so helpful & honest in helping us with our ordering. I wish that I could remember her name because of how friendly & helpful she was.
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😄
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.
Anniversary Dinner at Oliver & Julienne - A Wonderful Experience
We came to Siam, welcomed by our servers, Oliver & Julienne, to celebrate a friends anniversary, & it couldn't have been a better choice. Despite serving a large party of around 30-40 guests that night, the staff remained incredibly attentive & hospitable. They checked in with us regularly to make sure everything was perfect.
The food was absolutely amazing-every dish was full of flavor & beautifully presented. I especially like the seafood curry. The wine recommendations were spot-on, & they even let me sample a few before choosing the one I liked best.
The team's energy & friendliness truly stood out. You can tell they love what they do, & it made the entire evening feel warm & welcoming. We'll definitely be coming back!
Best smelling & tasting Thai I have had since visiting Thailand. Authentic & flavorful green curry. The panang curry (2nd visit) was rich with superbly tender beef. A great staff & wonderful atmosphere. Will definitely be by on next visit to Montreal.
I dined at Siam to celebrate my 23rd birthday & I have to say I thoroughly enjoyed myself! From the service to the overall ambience, I would definitely recommend this restaurant to anybody looking for great Thai food with a modern twist. My green curry was really good &, the service was five stars. I had an amazing server (Fanny) & she served my big group of 10 people flawlessly. She was super sweet & very accommodating! Near the end, another server also came & upped my experience even more with his overall great personality & fun vibes (shoutout Olivier)! Thank you Siam for the amazing balance between a great restaurant experience, & a fun time! I've eaten at this restaurant twice already & will definitely be coming back. 🥂
