Sorry to be a moaner but I had spagetti bolognaise here and it was not very nice (i.e its put me off it for quite a while!), nevertheless to say, we didn't go there again.
By the way Kefalonia is about the same, if not more expensive than the UK.
This was an amazing beach, and well worth a trip. I think its even nicer than any picture suggests.
It's pebbly and can be a bit painful getting in and out but lovely scenery and not too busy either.
If you have kids, be wary of the undercurrent.
Me & my boyfriend have just come back from Lassi. I thought it was a lovely resort with beautiful views out over towards Lixouri. Argostoli is lovely to walk into and is again very scenic. We would recommend La Gondola in the square, pricey but good food etc. I think some other islands waiters etc may make more of a fuss of you as we only got a free shot of Brandy in the Trata, and nowhere else!
As for the guide price list on the lassi homepage, what a joke, double those figures and you're getting close to how expensive everything is. I found it to be the same or more expensive than the UK. Thats my only major complaint, so bring twice the amount of money than you think.
