I rarely had a chance to have a family dinner together, since my sister is working in Jakarta, so she only came back once a year at December. So we used this chance to have a family dinner at IBC, near Hyatt Hotel. It's quite far from my house (around 20 minutes using car), but the food is good enough for us. We enjoyed the dinner and in the end, it's not that expensive.
I hope you also enjoy the time spent with your family in this holidays
