Business dinners are an incredibly useful way to build relationships and a good rapport. Meeting in a more informal setting means you can get to know people better on both a personal and professional level, which helps with future negotiations and business dealings. For that reason, you need to think carefully about the venue in order to make sure everyone is at ease and has an enjoyable time.
Firstly, you need to pick somewhere which is conveniently located so none of your guests has too far to travel. Also think about the venue's links to public transport. If people are drinking, they're not going to be coming by car and will need easy access to trains or buses.
Secondly, think about dietary requirements. People follow all sorts of diets, for personal and religious reasons. It's important you research the menu beforehand and ensure it covers a broad range of dietary requests – vegetarian, vegan, gluten-free and all other needs. The last thing you want is a guest who can't find anything to eat.
Also think about the cost. As the host, it's polite to foot the bill but some people will insist on paying their way. Declining their offer too many times might seem rude. Look for somewhere which is the very upper end of reasonably priced – you want the food quality, but if others are paying, you also want it to be affordable and not so expensive they feel uncomfortable.
The right venue can be the key to building a strong working relationship. Research carefully before you choose and see things as your guests would see them.
