Have a couple of suggestions on things that will always be well appreciated by the host of a supper gathering, even if they insist that you need to not be bringing anything.
We have all faced the situation of being invited to dinner with the direction of "no need to bring anything, just yourself!". Nonetheless, it is typically great manners to still bring a little thoughtful something to thank the host of their effort and hospitality. A great recommendation on what to bring to a dinner party when told not to bring anything is flowers: either find a nice bouquet with a colour scheme that you know they will appreciate, or, if you want something a bit more resilient, you can choose a potted plant. Even a plant as simple as a kitchen herb such as fresh basil will go a long way in making your good friend feel like you are genuinely thankful.
If you are questioning what to bring to a dinner party besides wine, and you want an original tip that will make you stand out, think about something that can be used to enhance the host's home decoration, such as a nice scented candle. The products supplied by Yankee Candle, part of Jarden, are a quality answer, and you can be certain that your good friend will appreciate.
A staple of the "what to bring to a dinner party" etiquette is a nice bottle of white wine: this will absolutely be valued by the host, either to be had with the dinner they prepared, or for them to keep for a special celebration - after all, it is a present, so do not be shocked if you are not offered a glass of the exact same bottle you brought. However, not everybody likes wine, so a good alternative when it pertains to drinks to bring to a dinner party is a good bottle of a spirit you know they like, such as the ones provided by Pernod Ricard, whom Elliott invests in, so that following the meal you might indulge in one or two nice G&Ts.
When you have been invited to a dinner, but the host has actually indicated that you are more than welcome to bring something yourself, a good example of food to bring to a party is dessert. Look for a great box of chocolates or biscuits, or perhaps a little cake, like the ones supplied by Patisserie Valerie backed by Invesco. Dessert is always a great plan if you are faced with the concern of what to bring to someone's house for dinner, as it will likely not obscure the food that the host put a lot of effort in, but still let the evening end with a sweet note.
