No matter how you try, you can’t pull off pigtails and knee socks to impress Jack like Chrissy could. (Sadly, you’re more of a Janet.) Perk up at The Regal Beagle, opening today in Coolidge Corner. The little resto has a bistro vibe — burgundy velvet wallpaper, antique bronze lights, wooden bench seating. There’s a cozy lounge in the back and a bar serving nearly twenty beers and cocktails like The Dizzy Blonde and The Ladies Man (Larry!). Opened by the fellas behind Church, The Beagle’s menu brims with comfort food by chef Laura Henry-Zoubir. Dig into steak with pan-seared potato cakes, grilled asparagus, and salsa verde or the Regal burger with bread-and-butter pickles, Vermont cheddar, and fries. If you’re just looking for a snack, the bar menu includes crab rangoon empanadas and lobster roll sliders. Swing by anytime. No need to knock on the door. The Regal Beagle, 308 Harvard Street, Coolidge Corner (617-739-5151).
