If tacos are your thing, pass on Costal Taco. I can't help but compare most tacos in Cleveland to Barrio, and unfortunately these do not come close. They small and unsatisfying for the price.
However, this silver lining to Costal Taco is their location. The outdoor patio overlooks the Flats and is great for a nice summer/fall night of drinking. I came for a friend's birthday and we had a great time playing with their outdoor jumbo Jenga sets!
My advice: if you're coming to Costal Taco, eat before and just enjoy drinks and a beautiful view of the Cuyahoga river!
