To be honest:
I find this despicable - unless they serve a really low-end wine.
Despicable not because I have a problem with anyone using bottles... to each his own... but it always angers me to see good food & drink wasted or not served correctly.
That is like those douche-bags diluting good red with coke... damn.
A good wine needs a good glass - but certainly not a plastic bottle and no air to breath.
I looked this place up on tripadvisor .. and here's what is amongst the ratings:
tripadvisor rating said:
The wine is disgusting, the fondue uneatable and the staff very unfriendly. Not to mention the place in itself: stick one each other and very noisy. AVOID it
