Small but a nice use of space. Food is well prepared, good proportions and the little shop is well decorated. I have been to a few Thai restraints lately and had a hard time tasting the spiciness but, at Tum Nak Thai, they do not short you. I like hot food and I recommend medium, you can taste your food and still get some gradual heat as you eat. Favorite dish is the Pad Thai, my soon to be wife likes the hot and sour soup. If I had to say something negative...I have had better tom ka soup.
It is tuck away between Starbucks and Weight Watchers, if you know the area, they took over Samurai Sam location. Maybe 8 tables in a location that used to be a fast food restaurant
