It seems that the owners of Thai Style noodle house like to compete with other Thai restaurants. Their location in Chinatown is surrounded by Thai places and on Fort Apache theres an abundant amount of Thai places. I don't think TSNH is a knock out for the other restaurants its competing against, but its cheap.
The value of the items you order is a great bang for the buck and they have a large variety of noodles. Although it always weirds me out when I see a Thai restaurant sell won ton noodles.
Sometimes the wait time is a bit long (I see an elderly thai lady working in the kitchen which is a good and bad thing). If you come here in a party, I would probably skip the chef specials, not because they're not good, but because you'll probably be waiting another 10 minutes or so while your friends are grubbing.
Oh yeah, I find it a little weird that not all their drinking glasses are the same color. I think its a little weird when we get 7 waters and 3 are in clear glasses while the other 4 are in red.
The service is nice though, never really had a problem with any orders.
THE SUMMARY:
cheap, variety, long wait, weird cups, decent service.
