Small Bites: Test Kitchen Tuesdays at Corkbar and National Doughnut Day

$2 Tuesdays: Ricotta and Parmesan-Asiago butter "raviolo" with sautéed broccoli rabe and brown butter. That's the dish du jour as Corkbar today kicks off Test Kitchen Tuesdays, in which chef Albert Aviles tests an appetizer-sized portion of a new, market-driven dish not available on the regular menu, for only $2. (Available as long as ingredients last.) Corkbar: 403 W. 12th St., L.A. (213) 746-0050, www.corkbar.com.

Free Doughnuts: In honor of National Doughnut Day on Friday, Krispy Kreme stores in the greater L.A. area will give every customer one free doughnut. Check the website for the location closest to you. www.krispykreme.com.
