Le Petit Dek Sen is described as delivering authentic Thai flavors with a homey, family run feel, where tofu and vegetarian options are standout and spice levels can be adjusted to taste; the atmosphere is welcoming and the staff are friendly and the space is clean, though a few reviews note a work in progress on vibes and a repetitive music track. Service is usually polite and efficient for appetizers, but occasional delays for mains are blamed on a busy kitchen and online orders, with delivery reported as delicious when it arrives. The restaurant is regarded as a hidden gem in Montreal, good for casual dine in or takeout, with portions that satisfy and flavors that can evoke Thailand, inviting repeat visits from diners seeking authentic Thai cuisine.
Food was exceptional. Service was super warm & attentive. Come hungry & order lots of different dishes. Probably my new favourite mango sticky rice in Montreal (& I've tried a lot of spots).

Good prices, & filling portions.
Taste : Plates were not spicy enough, we requested extra chillies to complement the meal. Fried egg was room temperature.
Service : my only real complaint is about the slow service despite us being the only customers there…taking orders, prepping food, everything took way too long. We saw the chef leave the restaurant then come back to prepare our mains, leaving about 30 mins wait between our appetizers & main dishes.
We got the appetizers right away, but waited an hour for the main dishes which never came. Asked for take-out instead (another 10 mins.). I guess the reason was they had one cook & there were a lot of delivery orders. The waitress was very nice. The music, unfortunately it was stuck on one song that played over & over.'Nothing's Gonna Stop Us Now', quite funny thinking about it now.
Came in here looking for vegan food, the chef cooked me up dinner with a big smile & it was ready in the blink of an eye. I've been vegetarian for 15 years & this might be the best tofu i've ever had.
I was impressed with the taste of the food, just like eating in Thailand. The food was delicious, the staff were polite & friendly, & the restaurant was clean. I will go back to eat again.
Le Petit Dek sen.. is an authentic that food. Hidden gem in Montreal.. We order some appetizers, Somtum & TomYum noodle soup is the best !!! The staff is very nice & our server very friendly! If you visiting Montreal & craving Asian food!! Don't missed out .. I'm recommend 👍🏼
Really great Thai food. Just newly opened (sister restaurant to Dek Sen in the plateau), so very quiet. Flavours were spot on. Portions were a good size. Would recommend for casual sit down or take out.
