And that question is can you have your entree at one restaurant, then saunter over to another and have dessert there?
This may have indeed been asked in the past, but I don't recall seeing it, so my bad if this is a repeat. And of course I already know this does not apply to the restaurants where reservations are required - well at least as far as being the 2nd place as posed in the question, that is.
FYI, this is more of a curiosity question than anything. Not saying if Couples allows this we'd be jumping back & forth place every night, but who knows? Maybe on a given night dessert at another establishment is more appealing than where we're having dinner.
Reading is fundamental. It's just that for some, it's more mental than fun.
