An open house is simply a way to get people excited by doing something different and unexpected. You need to continually get fresh people through the doors of your business and this is an easy way to do that. You can call the event whatever that you want, but the idea is something new and exciting in your business. You can have a lot of fun with this if you are doing it in your eatery, because of the uniqueness of the space.
Generally a place like a cafe or coffee shop is perfect for certain types of things, like an art opening or poetry readings, because of the space. You have tables and space for people and wall space also. If you want to get people in there each month to see the new work or show then you can do this with an opening that will show off the work of whatever artist that you have picked for this. If you have some of your own items like t-shirts or hats for purchase at this event then you will be able to sell some of these then.
Having your own promotional products for sale at your business is a nice way to generate more revenue and to get your logo out in public to get more exposure. You would be surprised by the amount of people that will actually buy a hat or shirt, or even folders and tote bags with your logo on it if it has an attractive design. These items also can make some impressive giveaways. You could grab one or two of these to give to someone that has just spent a good amount of money with you and they will be impressed.
There are many places online that sell these products and they will help you to get more ideas about which ones that you want to use and also how you might want to customize them. You will find things that will make people think about your company. Coffee shops will do well with selling customers refillable travel mugs because they are so useful. Clothing is always good, especially if you have a particularly nice logo to put on it.
