If I want to take a bus to the Big Buddha from Tung Chung station

Is it correct that the bus number is 23? We want to take the bus to the big Buddha some times after 12.00 a.m. what is the bus schedule? And if we go there after 12.00 a.m will there be vegetarian meal by that time? Would there be enough time for us to sight see the place if we only want to see the big Buddha and have vegetarian meal?

Thank you
