Blue & White Cafe is reputedly the original and the best, so there was no better opportunity to try it. I suppose eating this at 3am after a few drinks would enhance the experience, but it's always a good test of hangover food to try it when sober. For lunch. At 2pm.
Overall the dish is pretty average - standard chips (not as crispy on the outside as I prefer), relatively tasty lamb (not as tender or flavoursome as the souvlaki's in Melbourne I'm used to) with some garlic and chilli sauce layered on top. It isn't bad by any means, and the combination has promise, but better chips and meat would certainly elevate this further.
In any case it's always worth trying the local cuisine.
