the town centre and shopping centres are too expensive for a small business. my opinion.
There is no other option unless you want to go out of business in a years time.
there will be a new restaurant on the river soon. u could try something similar.
Do tell ;)
Acquario, on top of Monopol, is doing extremely well btw.
some sort of student bar/food place. cheap with fast turn around
The problem with "cheap", is that you'll never be able to get the prices down to that of your well connected competition. The race to the bottom is a painful one.
I'm not sure of the breakfast thing, outside of hotels I just don't see Polish people having breakfast in a sit down restaurant on their way to work... It seems like a lot of overhead with not much possible return. I'd start off from 12 noon at the earliest and only try breakfast on a trial basis once things are up and running and going okay.
Depends on where you're at. If you're close to the hotels, you get people who are skipping the €20 buffets. If you're close to offices, you bill yourself as a place for morning meetings. It works surprisingly well in Prague :) Plus, it's not much overhead, you've already got staff in doing prep work, might as well have some bare bones waitstaff to open and do the day to day stuff like take deliveries, inventory, reordering, all that good stuff.
