Barklays

The best spot ever
Try any burger they are all awesome
The mozzarella burger is my favorite
They have happy hour until 1/2am on Fridays and Saturdays
Su he a nice affordable place with awesome waitresses and waiter ;)

The food is fantastic and the service is exceptionally friendly. Definitely would come back for drinks and a bite to eat if I stayed in Paris longer

Nice staff and the happy hour from 6-9pm is awesome. On the weekend (Friday, Saturday) the happy hour is until 2 am or so. During the happy hour a beer is 3.50€ and a great variety of cocktails about the same price. You can sit outside and even with a large group of people you'll find good place with tables in the back.
