Restaurant at the End of the Universe was not as good as A Hitchhiker's Guide to the Galaxy, but it wasn't a disappointing sequel by any means. (Except for that part with Marvin) No spoilers, but if you've read this you know what I'm talking about! Arthur was the focus of this first book and I was happy to get to know Ford Prefect and Zaphod a bit better with this one. I cannot recommend this series enough, it is always sure to be a great adventure with plenty of laughs along the way!
