Consider restaurants, function rooms, or bars for a birthday party with friends and family if you want to spend a few hours celebrating. Warehouses offer flexibility and are great for larger events at a more affordable price than restaurants; however, you'll likely need to arrange catering. In the summer, outdoor spaces like gardens or patios are perfect for tropical-themed birthdays, picnics, or happy hours with friends.
There are several things to consider when planning a birthday, such as the type of event you want, such as dinner, dance or casual gathering. Think about the guest list size and what the birthday celebrant enjoys. Don't forget to plan for entertainment and accessibility, and choose a convenient location.
