When the owners of O'Reilly 304 wanted to expand their increasingly popular restaurant a few years back, they opened another one directly across the street and amusingly called it El del Frente ('The One in Front'). It's more of the same culinary genius, with a few bonuses – a roof terrace, retro 1950s design features and heady gin cocktails.
Partake in the lobster tacos, octopus salad or drinks from what are possibly Havana's best mixologists and enjoy it all under the stars. The entrance is through a modest door in Calle O'Reilly. Book ahead; it's insanely popular.
