Don’t go walking into the Breakfast Club expecting to see Ally Sheedy, Emilio Estevez, Molly Ringwald, or any of your other favorite actors from the 1985 movie of the same name. This Breakfast Club is less ’80s icon, more ’50s throwback — though it’s been around only since last year. With its vinyl-covered booths, chrome stools, counter, and chipped plastic glasses, the Allston restaurant screams classic diner. Yet there’s a dichotomy here: for every vintage touch, there’s an equally modern twist, like egg-white omelets and a fax machine.

The Breakfast Club’s clientele is similarly diverse. Families crowd into booths behind groups of hooded-sweatshirted teens nursing hangovers. And a waitress seems to know them all, clearing their plates and shooing the boys out with a cheerful " I’ll kick your ass. Come give me a hug! "

As for the food, the diner is exactly what its name implies: a place for a hearty breakfast. Three-egg omelets — including veggie ($5.95), Western ($5.75), and Supreme ($4.95) — come with crunchy home fries and toast. Thick-cut French toast ($3.50) is three pieces dusted with cinnamon and powdered sugar. A board advertises daily specials; when available, go for the chocolate-chip pancakes ($4.95), three large flapjacks that are equal parts breakfast and dessert.

Lest you worry that the Breakfast Club has forsaken its namesake completely, fear not: " Library Specials " include " The Dork " ($3.25), two eggs any style with home fries and toast; " The Princess " ($4.95), a Belgian waffle topped with fresh fruit and whipped cream; " The Jock " ($5.25), scrambled egg-white omelet with veggies and wheat toast; and " Detention " ($7.95), two eggs any style with steak tips, served with home fries and toast.

And in a nod to those who’ve already enjoyed their first meal of the day, club sandwiches, lunch plates, soups, and salads are also available. Saturday detention was never so tasty.
