Fantastic Thai food and great staff - a winning combination! I had the Gaeng Hunglay - pork belly (also available with ox tail) and a ginger curry rub in a clay pot, served with rice. I've never seen it on a menu before and it was recommended so I had to give it a try. I also ordered the Pad Thai. Too much food for sure, but when I go to a new Thai place, I always want to sample a couple of things. Both were prepared simply and were really exceptional. The menu is a little limited - only about 20 items including starters and mains. This is good I think. It means the things that are on the menu are done very well. It's apparent there is a lot of attention paid to the offerings here.
Speaking of staff, everyone was really friendly and helpful. I sat at the bar, so I saw more of them than I would have had I been at a table. No fewer than 4 people asked me how I enjoyed my meal. They've only been open about a month so enthusiasm is very high. I get the sense that everyone is fairly dedicated to the chef, the concept and the idea that they are bringing authentic and delicious Thai cuisine.
Pai reminds me a lot of Pok Pok - Andy Ricker's incredible top Thai place in Portland Oregon.
