Third wheels are a drag.

Always wanting to split the bill three ways. Getting in the way of a good makeout session. And they really screw up a three-legged race.

But in the case of Terzo (that’s “third” in Italian), the brand new restaurant from Nice Ventures (the peeps behind Rose Pistola and Rose’s Cafe) opening tomorrow, the third time’s a charm.

Located just across the street from Rose’s Cafe in the space that formerly housed Pane e Vino, the cozy eatery features a zinc bar, exposed brick, and a working fireplace. Alight on one of the espresso-brown leather banquettes and take a peek at what’s going on in the open kitchen.

Speaking of, chef Mark Gordon will serve up pan-Mediterranean small plates like grilled halibut with fava beans, Moroccan pea soup with spicy yogurt, and arugula salad with pine nuts and Pecorino. Wash it down with one of the ever-changing 50-bottles of wine, sangria, or an egg cream.

Definitely worth checking out, even if you are just tagging along.

Terzo, 3011 Steiner Street, at Union Street (415-441-3200 or terzosf.com).
