O-toushi/お通しis actually a bit difficult to translate.
In a Japanese (in Japan) izakaya it is an appetizer that is served with the first drink and that you pay for in general in lieu of a cover charge.
I have nothing against such a notion as it gives you a good idea of the chef’s skills!

Last night Dragon treated me to a double marinade!

vegetables marinade consisting of vegetables cut in sticks of the same size:
Ha shooga/fresh leaf ginger, myoga/Myoga ginger, cucumber marinated in olive oil, rice vinegar and what else served with homemade miso umeboshi and sprinkled with black sesame seeds!

as for the mussles she had some boiled and frozen in the refrigerator.
After thawing them she stir-fried them in olive oil, vinegar and chilies and served them sprinlkled with some finely chopped scallions!

Great with sake!
