Best yellow curry meal I've had in a long time!! Chicken or tofu were the options...I ordered tofu. Rice was a bit stickier than I like but the coconut curry sauce was to-die-for! It could have been spicier but was I still very pleased. The fried tofu was also delicious but the ratio of dipping sauce to fried tofu pieces was off...needed more sauce. But still a very good dining experience. Small seating area and huge TV mounted on the wall, available for your viewing pleasure. Nice people and good service! Highly recommend!

The beef salad was really good. But be warned. The spicy chili that they put in it is spicy! My tounge was burning. For a couple of minutes 🥵. My stomach also felt like if it had a ball of fire inside 😬. My stomach was not in pain. But it just felt uncomfortable having my stomach with a burning sensation it almost felt like a fire pit 😅. For 5 hours working like that. Next time I will order the spicy chili on the side so i can eat alittle bit of it. If anyone gets this spicy beef salad remember to get a cup or 2 of extra cold water. It does taste good. But it just felt like to much fire 🔥🔥🔥. The ice tea was great! Tasty too! I liked it very much. What kinda spicy chili was in this? It was good. In the picture I took on here it seems like there was not a lot of the chili added but it is spicy. Even though it is hard to tell if it is even in there. I appreciate the service here. Good beef salad.

This place is authentic. I'm always a little nervous about trying Thai restaurants, mostly because they end up being average. Not this place. I ordered egg rolls and shrimp for an appetizer. Both of these are deep fried but we're so light and didn't taste heavy or greasy. The ramen has some of the best flavor I've ever had.

Small But Mighty little restaurant with outstanding service and delicious food. Good size servings of freshly made dishes. Hidden in a commercial center. Thank you to my niece Jessica for my birthday lunch it was wonderful and delicious. If you like Thai food this is the place very reasonable prices can't wait to return try some of the soups

The waitress was very courteous and polite, and the food was incredible at a very affordable price. I eat a lot of Thai food, but this small restaurant had very fragrant, fresh flavors. I don't know what the previous reviewers were talking about, but there is seating (but few tables). You can make reservations, but they have several tables available. Overall, it was a great experience and I highly recommend it.

Ordered Pad see ew with beef, & a Thai tea, which is my go to Thai food order. The food was great! It came with Chinese broccoli, which is the only kind of broccoli I like in this dish. My order came out super fast, & the server was very friendly. The Thai tea wasn't overly sweet, or artificial tasting, which was a pleasant surprise. I will definitely being coming back!

This restaurant is a hidden gem for sure. When we got there, I won't lie we were a bit surprised at the size of the dining area as we had a slightly large group but they seated us no problem and were very attentive when providing extra place settings. Immediately when we walked in, the woman at the counter greeted us very warmly and her service was just as kind throughout our experience. The food was excellent and we definitely recommend the Pad See Ew, the beef jerky, the grilled beef salad, and any of the fried rice. Everything was super flavorful and came out relatively quickly. This place was top notch!

I have been living in Ontario for the past 5 years and I have yet to find a tasty, authentic Thai food place near by. The quality of the food was fantastic, the price was great. By far, one of the best pad thais I’ve had in a very long time! Don’t even get me started on the Thai tea! Chefs kiss! The best, delicious, I should have gotten two! I will be back, with my kids this time!

This spot truly impressed me. I usually feel a bit unsure when trying Thai food since many places turn out to be just okay, but this one completely changed my expectations. I tried the egg rolls and shrimp as starters. Both were fried, yet they were amazingly light and never felt oily or heavy. Every bite tasted fresh and really well prepared. Overall, I enjoyed my visit a lot. I would happily come back and definitely recommend this place to others.

Great service! 🌟 As I enjoyed my meal, I noticed several returning customers, and our server remembered them, their orders, and greeted them so warmly. I’m sure her hospitality is part of the reason they keep coming back. 💕 I ordered the vegetable yellow curry with rice 🍛—the flavor was delicious! The potatoes were a bit overcooked for my taste, but overall it was a great dish. The Thai tea was nice and sweet 🍵. The restaurant also has cute little decorative touches ✨, making it a cozy spot to enjoy some good food. Highly recommend! 👍
