Jak's is a local steakhouse chain with locations also in West Seattle and Issaquah. It's one of my favorite dining options in the area with it's booths and wood paneled decor. In typical Seattle fashion, you'll see everyone from businessmen in ties to families in shorts and t-shirts.
The food is good and the service is friendly. My personal favorites on the menu are the double cut pork chop and the salmon. The portions are hearty and all come with a potato (mashed, baked, or pancakes), salad, and vegetables. One of the unwritten potato options is the "UFO" - a combo of mashed potatoes and the potato pancake. It's a must when you order to ask for the UFO.
Jak's is kid friendly and noisy enough that if your child is loud no one else will notice.
