Restaurant Loto is an asian restaurant that gives Barcelona, Spain a clear reason to appear on a dining shortlist. The draw is the kitchen's clarity, hospitality and consistency; at a casual value price point, it should be judged as a practical, value-minded stop with more character than a default booking. It is most compelling for diners seeking flavor, texture and a point of view rooted in cuisine rather than decor alone, especially if the night calls for something more considered than a safe default.
