I would probably say around 3.5-4. I am not a taco expert by any means but I will give this review my best shot :P
I got the spicy shrimp taco and the spicy octopus taco. I like spicy, and these were not spicy enough for me, even though I added their medium heat salsa verde. I should have gone with the spiciest but it said habaneros and garlic, I guess the word "habanero" scared me a little.
I don't have anything bad to say though about the shrimp taco. It was flavourful and I got a lot of servings of shrimp that were medium sized (at least more than 5 pieces). There wasn't anything that really stood out to me though. It was a well-rounded taco. The octopus taco was interesting, I think there was a slice of cactus in it? But if I was blindfolded, I wouldn't have known that there was cactus there. I should mention that it was a huge serving of a lot of stuff, a lot of it was falling out as I was biting into it. The octopus was pretty tender, but probably because it was sliced into very small pieces (which obviously helps).
My only complaint about the food is that my octopus taco seemed very oily.. I don't think it was sauce. I wasn't a fan of that. The waitress could have been a little more friendly as I asked her opinion on what I should order but it didn't bother me too much.
I would come again to try out their fish tacos.
