Organising your day at DRA (commute & lunch)

Hi, I just moved into DRA and was surprised to realise that there is no lunch on weekdays and no dinner on weekends.
As I have not lived in a place like St Andrews before, I would love to hear how other people at DRA organise themselves.

To me it seems that there are three aspects to consider:

1) Eating. Where do you eat if you can't get a meal at the DRA canteen and don't want to cook, in order to safe time?
Is there a university canteen in town which is available for every student, or are there only those for the main hall residents?

2) Studying spaces. Which places do you recommend do study or to just spend a productive day?

3) Commuting to the town centre or university facilities. While the walk is fun, I imagine that 30 minutes each way consumes a lot of time during busy periods.
Did you get a bike? I will probably try to find a cheap one or maybe even to buy an e-scooter.
Being able to rent scooters (ie Tier or Lime) would probably be incredibly helpful at St Andrews/DRA, but it seems that there isn't anything like this in St Andrews.
When looking into Google Maps, my impression was that there aren't many busses at DRA or that taking them would not save much time. But maybe I am mistaken.

All my questions basically link to how avoid losing time with the commute and lack of weekday lunches.
