When dining at Yoshinoya I never know how to ask for the size meal I want.
Their sizes are 並, 大, and 特.
I only know that "大" means big, but it also has two readings so I have no idea whether to ask for "dai" or "ooki". And since the word/character I know for "small" is not included, I assume they are using a similar gimmick to that seen in Western chains where there is no small but only "regular", "medium", "large"... sometimes up to the infamous "venti" (-:
Then again maybe there are various ways of writing "small".
So are these standard words or gimmicky like "venti", what do they mean literally, how do I know which reading to use for each, how would I say them in an order? Are these same sizes used just about everywhere in Japanese restaurants or are there some other terms I should also know?
