Is there anything better than slurping a gigantic milkshake while listening to Elvis Presley’s “Heartbreak Hotel?” I don’t think so. At a certain level, milkshakes are all about nostalgia, especially if you’re an adult, making you think of dime stores, ponytails, and jukeboxes. At Luna Park Cafe, there actually are jukeboxes, offering all the old hits. As for the milkshakes themselves, they’re so big that kids may not be able to finish even half of one. (Splitting a regular-sized milkshake is definitely a better deal than two smalls.) The variety of flavors is impressive, including pineapple, peanut butter, butterscotch, Oreo, and caramel. Better yet, you can make a combo out of as many flavors as you want, including the hot fudge on top. NINA SHAPIRO 2918 S.W. Avalon Way, 935-7250, lunaparkcafe.com
