I've been going here for many years.
5- 6 years ago I discovered this hidden gem in Regent Park. I had the sukhothai padthai and yellow curry. Holy cow it was delicious. I would order from this restaurant for take out literally 1-2 times every week. I tried every dish on the menu and loved it.
I didn't write a review at the time because the service back then was friggin horrible. Rude waitresses that didn't know how to give adequate customer service. I always said to myself that I would not go back because of the service..but the taste and flavour of the padthai was so distinct and good that I kept coming back like a drug addict looking to get her next fix.
I give this restaurant a 5 stars because after they renovate it, opened a 2 and then 3 location...the food was still amazing but the customer service got immensely better! The waitresses/waiters would actually smile! Love khao san road too and I always got superb service there, but sukhothai is closer to my neighbourhood so Im glad I stuck around to see the great service changes there. Good job to the management!
Must tries are to get the garlic chicken deep fries bites as an appetizer, and my favourite mains are the shrimp padthai, pad kee mao, khao soi, and even their version of "pho" is freaking delicious. Honestly...theres not one single item on their menu that I dislike..and I tried it all..many times. LOL.
