Cap'n Taco is okay, and it's rare to find a taco dive other than Taco Bell. It's located all by itself on Brookpark Rd. so don't pass it!
The tacos come overloaded with cheese and they do have a good flavor. The great thing is you can get beer if you dine-in, but the place is so dumpy, you're better off rolling with "to-go". I usually get some tacos to go on my way home from work.
We like em because they're different than other restaurants and they're yummy. But they do put a load of cheese on the tacos, which I'd prefer not to have.
Recommend - if you're looking for something more authentic than Taco Bell.
