Atmosphere was enjoyable. They attempt to replicate an old British pub with all wooden furnishings and Indonesian artwork, which was new to me for an 'old British pub'.
I had the sampler lineup with the Sleepy Hollow nut brown ale. My overall impression of the beers where very light in body. Yet, they were not watery or completely tasteless. As someone who likes big bold beers nothing stood out to me to mention here. So, instead I'd like to advocate Dad Watsons as a good lineup for a gateway into craft beer. Nothing's intimidating or difficult to understand in the beers. They're light, slightly sweet, and accent the style's well enough so you can tell the difference between a West Coast Pale Ale and India Pale Ale.
Dad Watsons is a nice place to kick back and have a few session ales with a friend who prefers wine or spirits. I would skip it in my Seattle Brewery Tour.
