We'll be honest. We went for the gelato but stayed for the accordion player, and when that beautiful septuagenarian belted "That's Amore," we had to wipe a tear from the corner of our eye. On Wednesday nights at Sonny's Gelato Café in Boca Raton, you too can be serenaded while relaxing outdoors, the wind caressing your hair as you lick a nutella and banana gelato. The Italian family who runs it knows their stuff — they've got creamy, sweet cassata Siciliana, stracciatella, and zuppa Inglese gelato — and it's all made healthy, with skim milk and not much fat. The only problem with Sonny's is that it tends to run out of things, as retirement home aids often schlep their entire crew over for an afternoon treat. It's therefore beneficial to show up early and often. You can't miss the mango-colored building on Federal Highway, just north of 20th Street. We also recommend the appetizers, soups, salads, panini, and classic Italian hot subs, served daily from 11 a.m. to 2:30 p.m.
