Went to Penrith Panthers after long long time. The place has been quite done up and a few choices of restaurants. The main RSL-type resto was Kelly's Bar and Kitchen. Serving portion quite generous and price very reasonable (i.e. cheaper than comparable places) - chicken schnitzel starting from $18 for 200 gm and $22 for 300 gm as examples.
Suggest to get a membership for $5, specially if you have a large group as you get about $2 off per dish as member pricing.
