sushi night

Tonight is going to be sushi night.

Putting '-night' after a food or activity shows that that is the plan for that evening.  In this case it is a night for eating sushi. Notice the following:

1. Tonight is old movie night for us.
   
2. You know that Sunday is always football night.
   

never quite sure

I'm never quite what any of it is.

If you are not certain about something or you have questions about it then you are not 'quite sure' about it. Notice the following:

1. She is never quite sure exactly where places are in the city.
   
2. Although I order the same thing every time I'm never quite sure what I'm going to get.
   

from that point on

From that point on, I'm not sure what anything else is.

This phrase is used to describe what happens after a certain moment or action, from a specific and into the future. Notice the following:

1. She was basically sick from that point on.
   
2. From that point on I never trusted her.
   

rolls

We also have rolls with sushi.

In this case, 'rolls' refers to sushi rolls, or pieces which have rice, seaweed paper, sushi fish and maybe other vegetables. Notice the following:

1. My favorite roll has salmon and cucumber.
   
2. I think we should get three or four different rolls.
   

vile

I think natto is the most vile, disgusting food there is.

If something tastes 'vile' is has an absolutely terrible taste. Notice the following:

1. Some of the health food drinks are absolutely vile.
   
2. I can't believe you can eat that, it's vile.
