I'm not sure about prices, but you might want to look into Ivan's restaurant (at the Catcha Falling Start Resort on the Cliffs) for their Bird's Nest dining or Night of 100 Candles.
We have done both night of 100 candles and Bird’s Nest. Both are amazing and and in my opinion worth the cost. The Bird’s Nest is under cover so no worries about rain. Night if 100 candles is not covered.
