polishing my diamond

I've re-drafted my script 3 times so far, having had different people read through it, the feedback had been good in general, storyline is apparently clear and simple, but scenes have had to be changed as I re-draft.

Polishing and polishing, despeartely wanting that diamond to outshine the moon.

For example, originally, there was a scene of the couple sitting at a cafe sharing a sundae on a mid summer day. That was the perfect scene for me, the perfect day out for a young couple.

Then I got feedback that perhaps I should take account of cultural references - and my friend was right - if they are British, why should they be sat at a French style cafe sharing a sundae?

So the alternative I'm considering, is either a walk by the river, or simply a picnic in the park whilst playing scrabble. It's a tough call to be fair, I'm trying to take into consideration all that is associated with the action.
I want to be able to portray the same feeling of 'sharing a sundae with a sweetheart at a cafe on a summer day' but do it British style - which involves perhaps a 99p flake cone.

but the practicality is I won't find an ice cream truck near a park(with relatively less people around it to make it more believable that it's in a park). I'm filming in winter, have to accept that grim bit of life.

It's a new thought, I think I'm going to sleep on it.
