Scared of awkward silences on dates

So there's this girl i like, in the group we flirt and i think she likes me. I have not really spoken to her properly or had a proper conversation yet. What i have learnt is that we have little in common yet i still find her attractive and i just want to meet up outside the group and talk. I'm afraid that because we have little in common there will be awkward silences. Do you think i should carry on going to the group and learn more about her and her interests, and then ask her out somewhere or simply go in and meet up hoping there won't be any awkward moments? What do you do when there is an awkward silence? Also, any possible first date ideas? (apart from the cinema) Cheers
