Kory would probably take you if you asked but here's the easiest way. Head west until you get to the little driveway leading to Frenchman's Reef. Just walk straight to the beach, head left (east) and the second (and largest) beach bar is Eggy's. He also has a sign, "Eggy's Bar". As you become more familar with the area you can walk through yards to reach it. Conversely you could go to Waikiki, head to the beach and take a right to Eggy's. If you are young and limber, you can follow the water from Jack Sprat (head west) but you will need to climb in spots and it's not a good idea to head back that way after some drinks.
