Was craving Thai food after seeing a google doodle about pad Thai, so a group of us found Sawasdee and made a stop in. Didn't realize it was mainly delivery/takeout, but luckily we were able to claim the single table they had inside! Two people appeared to be working tonight, with one running deliveries & pickups and the other doing the register, cooking, and pickups. While they seemed plenty busy, both employees were very friendly and welcoming, with the woman apologizing for wrapping our stuff up to go before realizing we were dining in (no big deal).
The food itself was decent - between the three of us we got pad thai w/ chicken, pad see-ew w/ chicken, and drunken noodles with tofu. The food came out pretty quickly and piping hot. The chicken was kind of dry and bland, but the noodles and vegetables were fine. The drunken noodles also got a thumbs up. 1-10 heat scale customization for each dish as well so you can get any item to your taste! This may not be our first pick for Thai food, especially if we are closer to some of the other good Thai places in the South Hills, but it's quick and friendly, and we'll definitely make another stop sometime to try out more items.
