Corporate events are definitely not just an opportunity to socialize. It is also an opportunity for companies to impress people and promote their business. Therefore, the organizers take care of every detail. Of course, this also includes catering for the guests and everyone present.
Apparently even gastronomic and catering services speak for the company's image. When a company can't even choose a good corporate catering company, how can potential investors be expected to decide on the real business issues?
When setting up a large corporate event, catering choices are very important. Though, the choice has to be made before the actual preparation. The bigger the event, the sooner choices have to be made. If possible, you should only work with the best providers.
This can be difficult if you don't know anyone or other companies that might qualify as such. You will need to use the internet to find out about catering companies in the city you are in. Learn about their abilities, especially to care for multiple people.
You can also ask your friends if they know of a company catering service that works well. You can get brochures and other written materials through certain vendors, but they are not very reliable.
If you want to make sure of your choice, check with the people the catering service caters to and find out if they are happy with the food and the service. Customer satisfaction is still the best indicator of gastronomic quality.
