I went to a buffet christmas party last year at a 5 star hotel and ate up!!!!

I dont eat seafood normally so that wasnt an issue for me.

Just be careful with the normal things on listeria list that you would avoid.

Generally these 5 star hotels are busy and have a quick turnover or meals, the one i went to had some thinsg cooked as you wait anyway eg pastas, stirfrys, nann bread and you could pick what was and wasnt in things, then they also had other things in ba maries.

Enjoy
