Hands down, the Thai House on Third Street, across from Valle's Market (which used to be Jack's IGA). I think it's the corner of Third and Magnetic...or it's close to there.
They have a great Pad Thai and several yummy currys. Yum.
This is my favorite place.
The Great Hunan, set back off US41 after the Westwood Mall, is pretty good, too...and it's Chinese.
There is also a Chinese Restaurant in Munising that is good. They have good Pad Thai, too. It's located on the corner of Superior (one block down--away from the lake-- from M-28) and Maple.
