Maybe I wasn't clear. We went there like 2 month ago and took a menu with us. Dishes were in the range of 400 DOP. I never assumed the prices for drinks could be that high taking into account the prices on their menu.
So when we stopped by there yesterday I wasn't asking for the menu (maybe to find out about some changes meanwhile applied...) since we did not came there to eat at 3:30 PM.
Well, lesson learned.
