Park Tavern. Atlantic Ave Delray Beach. Happy new Year! I am starting the new year strong in the burger category. Park Tavern on the trendy Atlantic Avenue in Delray Beach serves a chuck, short rib and prime rib mix burger that is delicious! This burger and fries costs $15 at dinner, $10 at happy hour and $5 on Mondays. It looks gorgeous. It tastes gorgeous. It is gorgeous. This burger gives one of my other favs, The Office burger, located across the street, a run for the money – Twinkie LaRue
