I guess is that this is not a creator's omission, but an intentional script.
The bar looks very cozy against the background of frosty winter. That's what makes it cool.
But the idea of a summer version is also interesting, but then a summer open veranda would look better. But it's hard for me to imagine the general interior.
And if you have an idea about it - write a general idea, maybe it will be seen and realized someday.
