Serenade - Martinis?

We were booked on the NCL Dawn for Oct. 2 week cruise out of Boston. Had to cancel due to a work conflict. So we went ahead and booked the Serenade sailing 9/23 to Bermuda. Haven't sailed on RCI in a few years. Went ahead and purchased the deluxe drink package for us. Which bar on the Serenade will have the best martinis? Also, saw that the drink package includes drinks up to $12. On NCL, espresso martinis were $18 and their drink package covers up to $15, so we paid the difference. What are the cost of these on RCI?

The vast majority of cocktails on the ship wll be within the limit of the Deluxe Beverage package. I've only seen a very few in the $14-$15 range, and those would likely be in the R Bar.

We just got off this ship last week. Typical Martinis were $12, and the best martinis were at the R Bar, on the 4th floor in the Centrum.
