Sonic Drive-In, 15640 Brookhurst St., Westminster, and 1632 N. Lemon St., Anaheim. Both open Sundays through Thursdays, 10 a.m. to midnight; Fridays and Saturdays till 1 a.m. (714) 531-8000. Nearly every aspect of this drive-in is perfect. From the Texas-size drinks (even the straws are big) to the bodaciously hot-to-handle onion rings and juicy hickory burgers. Pull in underneath the turquoise-and-white canopy, park next to a squawk box and order up.
