We're not saying Taco Tuesday is losing its touch or anything, but Thursdays are about to get a whole lot more interesting. Sherman Oaks mainstay Casa Vega is celebrating its 60th birthday with a tacos and tequila special every Thursday from now until June. Night owls (the promotion kicks in at 11pm) who order house specialty "The Boss" margarita ($13.50) can pair it with a 60 cent grilled chicken taco, a classic duo. The best part is, there is no limit to how many margaritas and tacos you can handle. Cheers!
