I can say that I've never had anything bad from Archi's. I love some good Thai food and Archi's will definitely hit the spot if you're looking for some good food!
I don't usually stray from my usual favorites which is Pad See Ew, Stuffed wings, papaya salad, yellow curry, and Rad Nar depending on what I'm feeling that day. I've had all of them at one point or another from Archi's and they were all delicious!
They do spicy levels from 1-10 and I haven't seen them "dumb" down the spicy levels like some restaurants do, which is a bonus. If you like a bit of kick without it being too hot I'd stick around the mid range, I typically go with 4 unless it's a good day. Although if you're used to spicy and love the heat definitely pump it up and you'll get what you're looking for.
I've never had bad service. They usually are able to keep it to the right amount of checking up on you without being too bothersome and make sure everything is good.
I've also never had anything too salty or oily like some Asian foods can be. They're definitely the place to go for good Thai food in town. The owners are also local so you're supporting another local business =]
