Festival of the Plain chairman Ian Chalmers said the popular annual event, running since 2006, offered free family entertainment, including use of the park’s upgraded playground.
"There’s something for everyone.
"It’s a family-friendly show," Mr Chalmers said.
For people who felt like shopping for a wide range of items, including food and decorative stones, more than 50 stalls were available.
Mr Chalmers said the successful switch back to the gardens park venue from Peter Johnstone Park was continuing in its second year.
Stall numbers were up on last year and more use had been made of nearby trees to provide shade for them.
Mosgiel couple Julieann Harris and Mike Smith enjoyed the food, including a hot dog, and also bought two garden ornaments.
The event was "pretty good", a happy day which had also enabled them to catch up with friends, they said.
Otago Neighbourhood Support regional co-ordinator Joy Davis, who also chairs the Mosgiel Taieri Community Board, said Party in the Park was a "fantastic" and readily accessible community event.
