Cake and Food
No birthday bash is complete without food and cake, and thus, while arranging any of these ideas, you will have to think about some yummy cake and food. Since most offices don't have arrangements for eating at the workstations, it is always advisable to arrange for food in the cafeteria, a terrace, or a balcony in the office. The best foods are appetizers as they are convenient to eat, aren't messy, and can fill you up for the day. You can include them in the breakfast and potluck ideas mentioned above as well. And for the birthday cake, order a funny and delicious one for your buddies.
