Some food places I have planned on my itinery for my upcoming Japan trip are those which I have learned of from tabelog.com, such as Kawazakanaryori hayakou (unagi), Tempura Iwa-i, and Tokudawara (Izakaya). Problem is, I don't speak Japanese and these places seem to be more popular amongst Japanese natives than your average non-foody tourist. Would this be very much of a problem?
I have thus far learnt my hiragana and katakana so I should be able to read off a simple menu, and will learn basic restaurant phrases for getting the menu / bill / lunch set etc. I can also speak Mandarin, so I should be able to communicate to a waitress if she is Chinese. Will this be enough for me to survive in such places?
