This is a small, open-kitchen, plastic-table-metal-chairs place In a strip-mall, so you know the ambiance. The food is fast & nice, and the take-out business is busy, and the staffers are pleasant, but we were the only and very cold eat-in diners on the night we visited. You order at the counter; you pay at the counter; you pick up your own food at the counter. When the door is open (which is often, as people come for their orders), that's a frosty breeze straight out of the busy parking lot: the food gets cold just as quick as you do.
Frank D is right: this is snack-style cafeteria service, although at least it is fresh. Use Thai Cuisine Experts for take-out and delivery, but don't bother with eat-in unless you're desperate.
