A well known restaurant in Kaliningrad - the most expensive menu item there in July was under 1k roubles, read, ~10 EUR at the time, most around 500 roubles - so 5 EUR.
Suffice to say a year ago they did not cost like 250-400, but about what they are now.
Or we can just look at Vkusno i Tochka, which you might remember as the rebrand of McDonalds:

You think it looks like they had 30% menu price increase, let alone 60?
