Mariscos Las Islitas cooks Nayarit-style seafood right in the heart of West Valley City. Pescado zarandeado (butterflied grilled fish), aguachile shrimp, and cocktails served in tall goblets are the dishes that define the house. Mixed botanas and ceviche tostadas work well for a group to share. The mood is upbeat, with music and a mostly Latino crowd on weekends.
