I hope I don't come across as picky or harsh, but I have some criticism that I hope you consider. I'm by no means some sort of pseudo-expert on dining out or anything, I'm just an everyday person who knows what's familiar! I haven't even eaten out in about a year, so if you can't relate I understand! The appearance of this building just doesn't seem 'right'. The exterior is a little industrial and lacking in form, as well as the interior being a little iffy. In my eyes, eateries fall into two broad sorts with their own 'feel' which I struggle to find with your lot:
The traditional, which usually has rich colours and older or 'outdated' décor, these tend to be decent and/or high end restaurants, pubs and British hotels/inns and certain foreign eateries (although many fall into the next category), usually ones serving Italian cuisine, Mexican or sometimes Chinese. These can also be those dodgy, tatty places that make you wonder why they haven't been shut down by safety and hygiene inspectors or went bust and the only reason the furniture is so old is because either a) in all their years of unsuccessful business they couldn't afford anything new nor to restore and preserve or b) it's the old thing they could afford out of the second (third?) hand shop or find in the junk yard.
The retro/modern, this is anything from McDonalds, diners and takeouts to those pretentious places that you or I will never be able to afford to eat in! 'Retro' places fall in this category because they are usually very contrasting to the traditional category. Basically, if the furniture is from any period from the 50's to the year 3011 with emphasis on looking clean or neat, and the decoration is minimalist, it's modern! These span from the worst to the best with all the rest in between, more so than their contrast!
These may also be a little more cheesy, which I think is a feel that a pizza place should have a bit of, even if just a tad, no whatever what category they fall into!
Pun not intended
There may be 'mixes', but they have a 'dominant' category that stands out more. I don't think that's possible to avoid in a mix. Use your best judgement to pick whichever feel 'suits' your pizza place more and try to make it seem genuine, like a place
you would eat in!
