#1 Clam Chowder vs Rice Pudding

Last night, I ate a clam chowder at seafood restaurant.
It was the first time to try it since honesty speaking I do not like clams and other shellfishes.
It was a big step to become a Bostonian since clam chowder is one of significant foods for Bostonian.

I also tried oysters.  Those were really nice.
As you know, oyster is one of shellfishes so it would not be _____  ___ my favorite foods, but somehow I like only fresh oysters.
Incidentally, it would be a great nourishment to recharge my energy.

Actually, we were supposed to go to a Brazilian restaurant because one of our teachers, who is from Brazil, recommend us to try a rice pudding.
Rice pudding, it sounds very interesting.  I would love to try it!
Unfortunately, our boss's request was ____   ___  seafood restaurant and her request was the most decisive because defiance against _____ boss might lead us ____   ___ deadly ending.  We were not eligible to choose…  We had better to be compliant subordinates.
Trying a rice pudding is still ____ ongoing  project.  The deadline of this project should be scheduled as soon as possible because I don't want to make it as a pending project.

During the dinner, my boss had been addressing about knowledge of wines, English, and so on.
The historical background of Japanese table manner was ___ very interesting topic.
Since I came to Boston, I have been feeling that I am a representative of Japan and my understanding of Japanese culture is superficial.   I could not explain why a glass for Japanese sake is smaller than ____ usual beer glass or a wine glass.  I was ashamed of myself.
My boss talked us about that story like a comedic storyteller.
I have noticed that a skill of storytelling is very significant for me as an envoy.
The dinner's atmosphere was very good and there was no tension.
I could understand why new ideas tend to be easily emerged during daily conversations than seemingly serious conferences.

Any way, it was ___ very precious dinner. (this is not sarcastic.)
