Boca Grande ("big mouth")and Boca Chica make an uber cool restaurant/bar establishment. Boca Grande is the modern tapas restuarant and Boca Chica is the 3 level bar next door. Great design, good food and fabulous (and pricey) Gin & Tonics.
And the coolest part of the whole place is its bathroom (blog 5 April 2012)
