A couple of weeks ago, we gave you a rundown on the summer cocktail menu at RA Sushi. Though it’s full of good options, there’s one that stands out as the most refreshing. Our Drink of the Week is the Cucumber Collins, guaranteed to give you a lift in this heat. Better still, it’s a low-calorie choice, sweetened with sugar-free Monin syrup, which — in addition to helping your bathing suit figure — means that the drink won’t cause a post-sugar, humidity-induced slump. Check out the cocktail recipe below, or head to Fells Point for one from the pros ($8).

½ oz. Monin sugar-free sweetener
