Even the best Thai places in the region seem to over-sweeten pad thai. Everyone I know who has visited Thailand has mentioned that the street food pad thai there is much less sweet.
Has anyone run into a Pad Thai in the DC region that isn't overly sweet? Thai Pilin in Tysons is my current favorite, but it is still a touch too sweet for me.
For those of you unfamiliar with Thai Pilin, it is not well-suited for a Chow lunch unles we went at very off-hours. It's an order at the counter, fight for a table sort of place, but the food is good. There aren't that many tables, there's a line out the door at lunch for takeout, and cold air blasts into the place unless you snared a back table.
I suspect that the cook may be from a different region of Thailand than most other places; the food has a certain earthiness and more use of some sort of fermented fish sauce than is common.
