50th birthday
By fifty, the guest list usually spans several chapters of a life: college friends, neighbors, people from work, and the partner who has heard every story already. The right room lets those groups mix instead of clustering in corners.
ERIA Marina, on Chestnut Street, pairs a full bar and gold-lit lounge with a proper dining room, so the night can open with drinks and move to dinner without anyone changing buildings.

Start with cocktails, then sit down
Guests arrive to a bar with a bartender already working and a lounge where people can find each other. Give it an hour before dinner and the room warms up on its own.
When dinner is called, the dining room is steps away, with banquet seating beside the bar so nobody feels sent off to a separate space.
A room that suits a mixed crowd
A fiftieth with colleagues in the room wants a different tone than a house party, and the Marina interior handles both. The marble, the pendant lighting and the arched windows read as grown-up without being formal.
For a larger group, Marina holds 400 standing indoors, which makes a cocktail-forward 50th with a long guest list realistic.
Let us handle the logistics
You should be at your own party, not managing it. ERIA coordinates the catering and beverage service so your evening runs on a plan you reviewed ahead of time.
