Both Jenny's and AhhBee's are on the West End Road, on the hill side. Jenny's is closer to the beach and AhhBee's is further up the road, a bit before Seastar Lane. I'd expect most taxis would know either one.

This map was invaluable to us on our first trip. Though a few places names have changed since it was last updated, much is correct and it really helps with getting around. Ahhbee's is relatively new, it is located were Alice's Restaurant was on this map.

I have copy in my camera case and almost never leave the resort without it. You just never know where the day might take you.
