Decent restaurant with good seafood. The servings were well portioned. We actually finished all our food. The ceviche had a great balance of citrus! I usually have to order extra limes on the side...

They close at random times and never answer their phone. Even though the seafood is good, it's pricier than other spots and I'd rather give my business and referrals to a more professional...
