Dumbo says yay for ñ, spin-off of super-narrow Soho tapas spot. Menu carries over, with plenty of sherries to wash down small plates of herring, croquettes, and spinach with currants and pine nuts. Octopus with paprika always a great date-night conversation starter. Basque accents to be added in menu's next wave. Serves late seven days, out of intimate basement space last occupied by Speak Low.
