More Than a Party Room

Some moments deserve more than the back corner of a restaurant. Riverside EpiCenter is a 113,000 square foot event venue in Mableton, minutes from Atlanta, where a twenty-guest shower and a milestone birthday for a few hundred get the same thing: a private room, food from our own kitchen, and somewhere for the night to go afterward.

Catering, setup, and staffing are handled by our own team, so nobody in your family spends the party refilling trays or watching the clock on a rental return. Audio visual, décor, and bar service are available in-house rather than sourced from companies that have never worked together.

Six bowling lanes, an arcade, and a rock wall sit elsewhere in the building and can be reserved as add-on time alongside your room. Larger groups rotate through in shifts while the party keeps going. Every room, setup, and starting rate is listed on our event spaces.

  • Milestone Birthdays
  • Quinceañeras
  • Sweet Sixteens
  • Anniversaries
  • Vow Renewals
  • Graduations
  • Baby Showers
  • Retirements
  • Family Reunions

Pricing

How Party Pricing Works

Room rates start where the space cards above show. Everything beyond the room is quoted to your event, so send us your date, your room, and a rough guest count and our events team comes back with a full quote within one business day.

Date and Day of Week
Fridays, Sundays, and weekdays carry lower demand than Saturdays, with the widest gap outside peak season.
Guest Count and Menu
Food and service scale per person, so headcount and service style move the total more than the room does.
What You Add
Bar service, audio visual, staging, reserved lane time, and extended setup windows each shape the final number.
