it seems that Denny's policies of service are the same worldwide. If you want slow service and to wait a while before you eat breakfast than Denny's is the place for you! (also dont drink the water)
Expensive for a Denny's. If you are visiting San Juan, go to a local place. Service was slow and the food was not that tasty (not that I am surprised).
Well, they have booze. But service is horrible. Dirty tables. Very slow to take orders. Even slower to bring them out. I have two starving kids who will not be coming back here.
