UK, Ireland / How long would it take for an English style restaurant in Poland to go bust? [80]

From my point of view, it will be better if you would consider:
1) Who will be your objective people? Businessmen, students, tourists, etc?
2) The style of your resaurant?
3) Your objective people will lead the the pricing, I think. And how about the gross margin you would like to get?
4) Your objective people also will lead the location. How many your objective people will pass by your restaurant?

Work / What jobs pay 10,000 zlotych per month? and Where can i find one? :o) [101]

From my point of view, average salary doesn't make sense. It just depends on the sample range. It is better to compare your incomes with those who are at your age, have the same education, live at the same place, have similar job. Average salary shouldn't be an excuse to stop you from finding a better job.

Around 10K pln per month is very possible to earn in Poland, if you are really qualified. At least I meet some people who get such payment, such as accountant, logistic mananger etc.

As for English teacher, I paid more than 2k pln for one-month polish learning, three times every week,1.5 hours per day. I had another 3 classmates meanwhile. And my language had lessons everyday. So I suppose his incomes should be more than 6k pln per month.
