Thanks for the replies.
Pete, you sure know how to kill a thread stone dead. Well, not quite as I feel compelled to reply.
You imply there is no consistency in the restaurant trade in Bulgaria. I have no doubt that standards vary from season to season with some, but not all. I'm sure that some restaurateurs want to excel and be consistent, that's how you build trade and the competition in popular locations like Nessebar / Sunny beach must be fierce.
The post I made was a feeler. Feedback provides a starting point and if these good people had a pleasant meal at certain named restaurants and wish to share in good faith their experience then I for one am prepared to pass on recommendations. The alternative is to go in blind. Having said that, that, I must admit, is my style as I regard everything as an adventure. But, my kids, on their first holiday without the influence of Mum and Dad are apprehensive and wanted some advice.
