Death is usually a symbol of change and transition. Its not necessarily a bad thing. In fact it could be good. However, good may mean necessary - not pleasant. The symbol of death does not have to be about a major issue. It may be related to something as simple as a new hair style or a new car. It may be more important and signal a change in your relationships with others or your self.
When ever you identify a symbol in your dream, an easy way to interpret it is by asking yourself "How am I like that?"; for example, "How am I like a doctor who dies in front of myself?" Does that mean you're kind of a push over?
A restuarant is a place where you eat and socialize, both can be associated with nuturing or seeking to fill a void within one's self.. To me a doctor is a healer. Since it was a male (presumably) it may relate to your masculine side. Perhaps you had a significant male figure who liked to help others (like a doctor, but not necessarily in a medical way).
So maybe your dream is telling you that you tend to nuture yourself in the wrong ways or that soon things will change how you nuture yourself.
