I am half Peruvian and have been lucky enough to visit Peru in several occasions. Unfortunately, I have only visited Lima and the immediate surroundings. In spite of my limited visits, I can share some recommendations.
One of my favorite places is the Barranco District. Although it is not too hip, the nightlife is great. There are many bars like Wayos and Mochileros, that cater a laid back and unassuming crowd. If you are a cannabis aficionado, you can smoke inside some bars but be sure to always ask your waiter or bartender before you start puffing away.
Miraflores is another awesome place to visit due to its implacable gardens, beaches and shops. In Miraflores you can also find the calle de las pizzas, a popular street with plenty of restaurants to chose from. In this street you can also witness how some locals try to charm and pick up foreigners for a ??good time??, at the expense of the foreigner??s pocket.
Well, those are a few recommendations if you plan to visit Lima. Goodluck!
