Translation:On the weekend he likes to go to a bar.
Why "in eine Bar" is translated by TO a bar. WhY not in a bar. I thought it would have been zu einem Bar. Thx
If you want to express that he goes to the bar to pick up a friend or he goes to the bar and stays outside (for what ever reason) than it is fine. If he 'visits' the bar, - goes inside you have to say " ...in eine Bar".
