Ya, the Sherry is really a treat. What has been said is true. Art Deco decor, cheap beer, a reasonably good location- it's North Miami so there is a bit of riff-raff around- and city busses can get you to and from South Beach without much trouble.
Breakfast was included in the price when I was there last, about 5 years ago. If you go early, you can catch it again before it closes around 11, which frees up more cash for the cheap beers around the pool.
All in all a good choice for crews on some downtime.
