No question the biggest missed spot is ESPN. Not even because the food was spectacular, or a great atmosphere - but because with Boardwalk being my home resort, it was great to have a spot for grabbing burgers, chili, sandwiches, with or without alcohol, in a casual sit-down spot that required no reservations.
Artist's Point in it's original incarnation - the first few years it opened it served a very exotic game menu - eventually it became more of a standard beef/chicken/seafood menu and was still a good restaurant, but those very early years it was an incredible and unique menu. There was an amazing plate with a sampling of multiple exotic meats that included bison steak, ostrich steak, antelope and one other I can't recall. The bison was great, but the ostrich blew me away...it was the first time ever trying ostrich and I have sought it out anywhere I could find it since - it is the most wonderfully rich, soft red meat - like a more filet-than-a-filet-mignon. Excellent Pacific Coast wines paired with the menu perfectly - the sommolier was very good with his pairings recommendations.
Other restaurants we regularly ate at that I miss include Concourse Steakhouse (now Contempo Cafe), Spoodles (now Trattoria Al Forno), Alfredo's (Now Tutto Italia), Empress Room (One of the dining rooms on the Empress Lily, now Paddlefish), Fireworks Factory (Approximately where Boathouse is now), Portobello Yacht Club (Now Terralina), Shutters (now Sebastian's).
