Holy... wow... sooooo good! I love Thai Place on Walnut down the street too, but Noodlehead is really freaking good!
At first I was bummed there wasn't Tom Kha soup on the menu, but it turns out that it's fine because the Chaing Mai Curry is like Tom Kha soup filled with delicious noodles and oh so freaking delicious!!! I've had the Street Noodle 1 as well and that was pretty dang delicious too. The Thai fried chicken is yummy!
A note on spiciness - I got a 3 and it was quite warm, but still good. I could probably eat a 4 but would be in pain, so I'm guessing that a 5 is way out of my league. This comes from a SoCal native married to an Indian, so I do spice and I do spice well - meaning, they're serious about their spice, but not crazy about it. But don't underestimate it either. (I'm rambling now, I'll skip to the rest...)
I think what's best is that you can tell that they really devote their time to making GOOD food and I think the limited menu helps with that. The dishes are presented well and are not overly oily.
This would be a great early date location as the ambiance is cool, but not too overbearing. And of course, it's super affordable BYOB - so yay wine!
