The theme and the number of guests coming are the most important aspects to planning your 21st birthday party in Philadelphia. For smaller parties of 50-100 guests, check out intimate spaces for private events. Restaurants, hotels, lounges, bars, and clubs all offer these venues with food, set up staff, and entertainment on the side.
Rooftop lounges offer unbeatable views of Philadelphia's skyline while riverfront cocktail bars have seafood and patios with waterfront views. For intimate parties where you want a touch of elegance, consider reserving a posh tea house or a brunch venue in downtown Philly.
For parties with large numbers of guests you'll want an event hall,
party hall, or banquet hall. Hotels are a good place to hold a major celebration at. Many Philadelphia hotels are also historic venues, which is reflected in the architecture and decor you'll find in their ballrooms and party halls.
