It's not something I would wear since I don't like Star Wars or wear anything with logos but sure, I have friends that wear that kind of thing to the pub. There are pretty much no rules theses days.
I would never wear something like that, but if you're going to a pub there's not really any rules so you can wear whatever you want so you'll be fine. If you're going to a bar or club though then I would wear something else.
All comes down to personal style. I wouldn't wear a t-shirt on a night out as it's too casual for me, but I have friends who would wear a t-shirt like that on a night out and it's fine.
