I lived in Thailand for most of my grade school and all of my high school years so I can confidently say that Sukho Thai makes awesome food. My boyfriend and I often order delivery, but have never eaten in.
Our usual order consists of the following: Shrimp Chips with Tamarind Sauce, Sukhothai Pad Thai, and Khao Soi with Beef. The Tamarind sauce that comes with the Shrimp Chips is so good. The Sukhothai Pad Thai is different from the typical authentic Pad Thai, but it is good and not ketchup-y in the slightest (a huge blunder when it comes to some restaurants' Pad Thai.) The one dish that truly stands out is the Khao Soi... it is addictive! We always order extra noodles so that there is enough for all the delicious sauce. Everything is always delivered well packaged and the Shrimp Chips are always nice and crispy upon arrival.
Delivery usually takes longer than your average delivery time - usually around 1 1/2 hours, I think, but it is well worth the wait.
