Yeah, that's not really the kind of experience that means much.
If this is the industry that you're really trying to get into, I would suggest becoming a bartender at an already established pub or bar and trying to work your way up to being a manager while soaking up everything you possibly can about how the business is ran.
I'm not saying it's impossible to start from scratch with little to no experience, other than reading some books or something, but learning it along the way will likely end in failure or a lot of mistakes that will hit you hard financially.
If you don't mind me asking, do you have any idea on how you would get funding for this business? It's definitely not cheap.
During the time when I used to work in a bar, we replaced our touchscreen ordering system and our sound system and I think those were somewhere in the ballpark of $60,000 and $15,000, respectively. I'm not saying every setup will cost that much (especially because the place I worked at was actually kind of large), but I'm just trying to show that things can get really expensive, really fast. Now just think about kitchen equipment, paying a contractor to remodel the place the way you want it, decor, televisions (I assume a pub would have them?), etc.
If you were to buy an already established business, so you could basically just walk in and change what you saw fit, you'd likely catch a little bit of a break over starting from nothing, but depending on what you want to change it could still get really expensive beyond the asking price from the previous owner.
The truth is, if you're posting "I'm thinking of starting a pub, does anyone have any tips on starting my own business?" instead of "How do I go about pricing food, any tips on how to find distributors, how do I get an ABC license, etc." it means that you have
a lot more research to do and experience to acquire before this idea would be feasible.
Best of luck, but I recommend that you do your research and think about this more before you start looking for a place to rent or buy for your new pub
