SaWadDee, on San Pablo in Richmond, has a few older references here (sometimes misspelled SaWaDee). I was taken to lunch there today by someone who works in Richmond. I had the lunch special of Pad Himmapan ($6.98), described accurately as stir fried chicken with roasted chili, cashew nuts, and onions served with rice (brown rice available). I really liked it; the flavors sparkled like good Thai food should. We sat on the left side of the restaurant at conventional tables. On the right side is an attractive area where you sit on the floor with your feet in a sunken space, which would be very nice for dinner. The staff members were unfailingly gracious. I'd stop there again anytime I'm in the area and try other things.
