I’m ordering food via a combination of Korean, English, and the old “point and smile” (depending on my familiarity of the food item). Prices are often listed so you can have an idea of what you’ll pay or a lot know enough English to at least tell you the number (or have a calculator).
I don’t know where you’re staying in Korea, but if you’ll be in Seoul, there shouldn’t be an issue. Tons of places have English menus or at least picture menus. But even with those that don’t, generally the ahjummas will have some limited English to make sure you get fed.
Even if you’re not staying in Seoul, any tourist place will have a few places with English menus (or at least translation).
As long as you’re willing to be a little brave, you will not go hungry.
EDIT: Sorry, I just saw you other part of the Saskatoon. Yes, a lot of street signs are in English, as well as other signed (subway, historical/tourist sites). So don’t stress and just prepare to have fun!
