The food was amazing. Generally in every thai restaurant yellow curry is good. But this specific restaurant's green curry was amazing. We did a level 5 spice and it was a treat to tastebuds. The service was exceptional. They helped me choose the correct spice level. The ambiance wasn't too great as it's a small place. The lighting and smell were so authentic thai.

I love the Thai Tom Yum soup, and my hubby gets the Pho. Both are SO GOOD! Great food and fast friendly service. Best Thai restaurant that we've tried in S. Arlington.

The chicken pad thai and penang curry were so delicious!!! This is our regular order and it is always consistently good. This is one of our favorite restaurants in Arlington!!

Good portions and tasty offerings. It's a whole in the wall with modest ambiance. Service was good as we got the food quickly.

After seeing the high yelp reviews plus the easy to find location we had to stop in. We were first in the door as soon as it opened so our service and food was quick. I was craving some soup with the cooler weather so Tom Kha to start with Teriyaki chicken as my entree. It was beyond good and hit the spot.

I'm really happy we stumbled into Sunny Thai. The food was very good and the service was outstanding. The entrees were very full of flavor, and the spice level was exactly how I would expect for what I ordered. I do think the salad rolls were just okay. They weren't bad, but mainly more of an edible utensil for the peanut sauce but didn't really do much on their own. The mango sticky rice was very good. Not too sweet, but just right. The warm sticky rice with the cool mango was also nice.

I had the beef pad kee mao and a Thai tea. The entree came with a cup of vegetable soup. Everything was good overall. The vegetable soup was fairly unremarkable but still a nice little bonus appetizer. The pad kee mao was a little too heavy on the sauce but otherwise good. I ordered a 3/5 on the spicy scale but it lacked the spice I was expecting at that level, especially for a traditionally spicy dish like pad kee mao. The Thai tea was likewise good but a little too heavy on the condensed milk. It came in a plastic boba cup. I personally prefer mine in a glass with ice and a spoon. It seems to taste better that way for some reason and the melting ice helps cut some of the sweetness. The inside is casual with tables and booths. They each accommodate 4 people if I remember right, though you can probably combine tables if you have a larger party. Overall, it's not the best Thai I've ever had, but it's above average and I would eat here again.

Stopped by as we were in the area and were hungry for lunch! Get the fried rice with pork at slice level 3... it was so good, couldn't put down my spoon, kept taking spoonfuls! Kids got pad thai with chicken and they really liked it staying that they want to come back here just for the pad Thai. I was happy to see vegetarian options, but do yourself a favor and pick the dumplings with meat. The veggie dumplings were too soft. I really wanted it to be flavorful.
