1st birthday party venues

Hey mamas, I’m looking for a cute space for a 1st birthday party for my son in December. I’m not really keen on village halls as we only want a small gathering of family and close friends. I’m looking for a small space or a play cafe or similar. Somewhere where the babies can play (maybe a soft play or I’ll hire it) and adults can have a glass of bubbles. We live in Rainham so anywhere in the Medway or Maidstone area. Thank you ☺️
