[中餐館] where can I go for 60tth birthday dinner for my mom?

'cuz of she just only prefer shanghainess food.. but any restaurant good for 30 people? don't want that expensive.. 'cuz I'm the one who pay for dinner, flowers, cake and the gift.. so broke..

my brother always so cheap.. just stay in hk don't bother to come back here celebrate with my mom.. always no gift..
