The food is much better in the dining room than the buffet if that was your question. Though we did find some nice things in the buffet. The dining room had the four courses that are offered for you to choose from. Yes, you may sit alone. They will ask if you prefer alone or with others and they will do their best to accomodate you. I'm not sure if there are a lot of tables for two, but if they run out of tables for two they will seat you at a table for 4 and let you eat alone if that is what you prefer. We ate alone most of
the time except on one formal night we chose to eat with another couple. This was on the Norwegian Sun in June of 2002.
