El Corazón del Mar is a three-story seafood restaurant in Roma Norte where the raw dishes - aguachiles in several versions, fresh ceviches, fried octopus with punchy salsas - genuinely work. On a weekday with an attentive server, it reads as a real neighborhood find. The problem is structural inconsistency: service times spiral, plates from the same table arrive staggered, and the paella is a mistake that appears on too many tables. The high online rating doesn't reflect what happens in practice; skip the cooked food, order raw, ask for Erick if he's working, and arrive between semana (weekday) at opening to avoid the wait.
El Corazón del Mar does aguachile better than most places in Roma Norte, and the pulpo al pastor is worth ordering alongside it. Skip the paella, go in knowing what you want, and this three-floor mariscos spot will treat you well
