T.P.
In short, she's playing you for a bedtime stall. My 2yr old does things like this to try and put off bedtime (throwing her lovey off the bed then crying it's "lost", wants socks off/on, needs to sit on the potty even though she just peed in her diaper, etc). I think a good rule is once teeth are brushed, no more food...so eat up at nighttime snack cause that's all you're getting. Let her have ice-water in an insulated mug by her bed in case she does get thirsty but that's it.
It actually helped my daughters nighttime wakeups wanting milk when we started leaving a sippy cup of water in bed with her. She would wake up thirsty and drink the sippy instead of crying for milk.
