Bump...because this place is an absolute gem and a totally ignored one at that, at least among most non-Thais. Thai home cooks and restaurants bring an almost endless array of prepared foods here. Some have English labels, some don't, but the always helpful staff will assist with explanations. But you can pretty much expect to find close to 100 individual items at any time, and more catered to the tastes of Thai folks than us farang.
The other day, I picked up a wonderful hor mok pla, along with a couple of Thai sweets. The woman who runs PNA asked me if I liked hot or mild, and when I said hot, she guided me to a different hor mok pla than the one I had picked up. It's phenomenal, better than any hor mok pla I've tasted in Chicago. Pretty much everything I get from PNA is that good. The elusive nam prik ong and nam prik noom are almost always found here. Some of the food tells you who made it, but much is a mystery.
The Thai dessert selection is spectacular. If you remember the old PS Bangkok buffet and their incredible sweet table, well . . . this is now the only place in town with Thai sweets at this level. Many are the kinds you'll find on the streets of Bangkok but would never, ever find at Thai restaurants here.
So head to PNA, bring your own bags, bring lots of food home and have yourself a Thai feast. You will be absolutely blown away. That this place remains largely a secret is just shocking to me. It's like the pot of gold at the end of a rainbow, hiding in plain sight. Oh, and while they're closed on Mondays, they otherwise keep lengthy hours.
