Most probably. The question is how much worse though. So far it does not look like a disaster. I don't know that, too. I would guess that an ordinary Crimean's income is lower than an average Westerner's one. Like, say, 1000$ a month, roundabout. And because it is a resort region, that income is very likely to be very uneven throughout the year. To compare apples to apples, here's a restaurant that not only serves but also delivers Ukrainian cuisine in Moscow. Don't know about Sydney, but those in New York can also try it. No prices shown on their page there though. I ate it. And yes, that post shows the eat-out meal prices in Russia out of both big cities & wilderness of taiga/tundra.
