Paradiso, El Born (Barcelona)
Paradiso hides behind a pastrami-shop fridge door in El Born and topped the World's 50 Best Bars list in 2022. Giacomo Giannotti's menu leans on rotary evaporators and clarified builds, and regulars on r/Barcelona point first-timers to the Supercool Martini. Book ahead, it fills by 8pm. For drinkers who want the showpiece and the craft in one room.
