(The name is a fake one, used because I’m uncomfortable using my real name online) bought Pad Thai (hope I spelt that right) and it was amazing, super delicious and flavorful. I only bought one but honestly I should’ve bought more, it was that good. The portion size was pretty big and left me full after. Customer service was great too! The restaurant has a cozy feel to it, it’s very inviting. Will definitely be coming back more frequently and with friends. I also bought some deserts last last visit, specifically coconut ice cream, fried banana, and mango rice, all three were delicious especially the ice cream! And I’m not even a fan of coconut ice cream but I love theirs. I think I found my new favorite spot! (The photo attached is after I already had a few bites, I forgot to take a picture before)

After heavy holiday feasts, I was craving for light comfort food. The papaya salad (I ordered the non-spicy one) and coconut soup with shrimp were so refreshing yet flavorful. My tummy was happy!
