There's a sliding scale of what counts as "Italian gelato." On one end is the airy, brightly-colored stuff piled high in mountains under glass — fine, but fundamentally a different product. On the other end is the real article: dense, served at a slightly warmer temperature than American ice cream, less sugar and less air, made daily in small batches, often by someone who learned to make it from someone who learned from someone in Italy. The Peninsula has four shops on that authentic end. Here they are.
1. Gelataio — San Carlos. An Italian-born gelatiere making small-batch gelato daily in downtown San Carlos. The pistachio uses imported Sicilian pistachios from Bronte (the gold standard). The stracciatella has hand-shaved chocolate folded in, not pre-fabricated chips. Order the affogato and you'll get espresso poured over the gelato at the counter, exactly as it's done in Italy. This is the Peninsula's clearest reference point for what authentic gelato should taste like.
2. Caffe Stellato — Burlingame. The newest of the four (2022), but quickly earning a 4.7★ following on Burlingame Avenue. Classic flavors done well — pistachio, hazelnut, tiramisu — plus rotating fruit sorbets that change with what's at the farmers market. The café side of the operation means you can also order an espresso, a glass of wine, or a panini, which makes it more of a dwell-here spot than a quick-scoop spot.
3. SF Gelateria — Redwood City. The name is misleading — it's on Broadway in downtown Redwood City, not in SF. Small-batch Italian-style gelato in a tight downtown footprint, the right pre- or post-dinner stop if you're at one of the Broadway restaurants. The tiramisu gelato is the standout — actual mascarpone, actual coffee, not a flavor-shaped suggestion.
4. Café Borrone — Menlo Park. The grandfather of the group. Borrone has been serving Italian-style gelato alongside its espresso bar since 1989, and the gelato counter is still tucked at the back like an afterthought you have to know about. It is not. The stracciatella and the lemon sorbet are both excellent, and on a warm Peninsula evening the patio with a gelato and an espresso is one of the great minor luxuries of living down here.
A practical note: real gelato has a shorter shelf life than American ice cream because of the lower butterfat. The shops above turn over inventory fast — if you visit at 3 pm on a Sunday and a flavor looks suspiciously perfect, ask when it was made. Good gelaterias will tell you that day. The four above all will.
