Out of the frying pan and into the fire. So it goes with Skillet, the much-loved burger and poutine joint that’s moving from its Airstream trailer to a brick-and-mortar in Capitol Hill. Expect the same top-shelf comfort cuisine with a little more elbow room and sunlight (the new space, which is located on the ground floor of a sleek new apartment building, has loads of windows). And cozy mint green booths, twirling pleather bar stools, and hanging skillet mobiles (naturally). The street-side vibe remains, but the menu has expanded to include breakfast, colorful salads, and a full line of scratch cocktails. Rotating dinner specials include meat loaf on Monday and steak frites on Friday. The standout is a deliciously unctuous wine- and beer-braised tender pot roast: That’s Wednesday. No more mess-down-the-front-of-your-shirt, grab-and-go lunches. The food has long deserved a temple to slow eating, and it finally has it. Skillet Diner, 1400 Union Street (206-420-7297 or skilletstreetfood.com).
