I love Thai food, and this is my favorite Thai restaurant. If I want decor then I go to Basil Thai in Lincoln, a truly beautiful setting. But Pattaya has better food, and is much more centrally located. If you are vegetarian, their tofu dishes are excellent. The food is healthy, and will awake your tastebuds. Don't go there if you just want to pig out. Order mild if you are not sure about the heat level, since this can't be measured. I usually order medium, but my wife wife gets mild and she claims she likes hot food.\r
Parking is occasionally inconvenient, but is easily overcome. I always order take-out, and the food is always fresh and waiting for me. As others have noted, for some reason it is very difficult to locate this place, even though it is right on Watt Ave, north of 80. It's tucked away in a strip mall, just south of A Street, in North Highlands.
Pros: Superb food, friendly staff, easy to get to (once you know where it is).
Cons: Ocasional need to park down the street.
