We had breakfast with an astronaut one time. It was on a launch day and it seemed like a good idea as we had to be there really early and had lots of time to kill.
While it was very interesting hearing all about what the astronauts get up to (the astronaut did a little talk) the food was dreadful. It was buffet style and everything was wheeled through to a little side room so it was a bit chaotic and very basic.
There was also a Q&A session at the end of it and a photo op.
If you have someone who is mad about space and really, really wants to meet an astronaut then it might be worth the money. Otherwise, probably not.
