Great food, great service, great ambiance.
I've been to Pai two times and both times I was delighted with my order! The first time I went was on a girls night out with coworkers and I ordered a Caesar to drink and the oxtail (I can't quite remember the name of it). It was basically a ceramic bowl with an oxtail stew. It came with a side of jasmine rice. I was very satisfied with this order. My meal had a lot of strong flavours and the need was braised well, the meat fell off the bones. And the rice was cooked to perfection.
The second time around I went I had the same experience in terms of customer service. I ordered the beed noodle soup this time. A must try. If you like noodles and beef, this is your dish! It was basically a bowl of pho, but a very elevated version that had different levels of flavour. It was very filling as well. Near the end of the bowl I was eating for gluttony as I couldn't stop but slurp up that soupy goodness! I generally don't drink the soup but this soup base was excellent. A lot for meat and a lot of noodles.
The prices here are also very reasonable and its a great place to just hang out with friends after work. But go early before 630 because that's she. It gets packed. And the added bonus here is that you can make reservations. A lot of the more popular Thai places downtown don't allow you to do so.
I will most likely return :)
