Croatia - whats it like and where to go

[Zippee]

We're looking to book a week away in July and are thinking about Croatia but know nothing about the place. Ideally we want beach resort, quietish but things to do, nice restaurants, some shops etc.
What resorts are good? Heard Split is OK?
Is it expensive to eat out there (presume they are Euro based in the main tourist areas?)
Places to see/visit?
Basically any advice would be massively appreciated.

Thanks all so far. We're looking to go mid July before the schools break up.
