I believe what you are asking is whether the voucher deal includes drinks... if yes, then the answer is no... you would need to buy drinks separately ... but if you are worrying whether you would be allowed to buy a drink if you use the entertainer voucher ... then yes, you can buy the drink separately on your visit when you use entertainer vouchers...!
Sorry if i got your question wrong...1
Latitude at the Jumeirah Beach Hotel do drinks packages and you can use Entertainer vouchers.
Chanels at the Media Rotana do buffets and I think you can get a drinks package which Entertainer Vouchers can be used for.
If you have the Gold Fine Dining then Flavours on Two at the Rotana on SZR is another option.
