Hard- & soft-shelled tacos, $0.99
Roll 'em in Doritos powder, and the plain-old tacos would be the best thing on T-Bell's menu. Since they're not, at $0.99 for both soft- and hard-shelled tacos, the second-best thing on the menu's a hell of a snag. Especially since they taste like Chipotle compared to ol' Jack in the Box.
Most filling: Carl's Jr. -- Their chicken sandwich doesn't require a side of more sandwiches.
The worst: Jack in the Box -- That these tacos are also marketed as sides is pretty alarming.
