Warwick University vs Kings college vs NYU (CAS)

Hello, I'm a student at a school in Europe and I have been admitted to NYU CAS and have offers from King's College London and Warwick University. Currently, I am trying to decide which uni should I attend but I'm having difficulties. I'm talking about undergraduate degrees, and I surely want to pursue an MBA at top schools in the US or at INSEAD. I am fascinated by Investment Banking and probably this is what I want to do later in my life (or real estate), after my master's degree. I'm considering NYU because it is the CAS and not Stern, and not only that but its cost is much higher than the other two. I would love living and study in NYC but I don't know if it is a city for an 18-year-old. I know Warwick is a great uni but I wouldn't want to live at Coventry since I have heard that it is miserable and I want to live in a big city, in order maybe to begin a start-up at either London or NYC, since I have many ideas. About King's, I know that its the worst uni of them all but it is cheaper than NYU and I prefer it to Warwick because it is in London rather than Coventry. I honestly would love to hear opinions from all of you to where to go, considering internship opportunities, uni life, masters degrees opportunities and finally job opportunities. Lastly, my father works at a bank in Europe and has many connections that would probably get me an interview at IB's in the UK (in the US he doesn't have any connections) and that's why I think going to Kings would be okay. Thank you very much
