Each features a beer-battered fish filet with tartar sauce but differ slightly with their greens and bun. 

The Carl's Jr. Beer-Battered Sandwich comes with shredded lettuce and a toasted plain bun, while the Hardee's version comes with leaf lettuce and a toasted sesame seed bun.

In terms of pricing, the suggested price for each sandwich is $3.29 (may vary) but Hardee's is also offering a two for $5 deal on them.
