Octopus is having its moment right now. You'll see it popping up on many menus around town, but if you want to try the cephalopod in the best possible conditions, you have to eat it at Virtù. Though Chef Gio Osso's menu changes all the time, you can always find the wood-grilled octopus somewhere on it, and that's because it quickly became his signature dish. The charred chunks of buttery, soft octopus have an addictingly smoky quality balanced by the acidity, spice, and saltiness of whatever other components Osso decides to pair with the meat. The texture of the octopus itself isn't rubbery, as you might expect, rather it's more like a cross between a rare steak and a lightly seared tuna. Fifteen dollars is a small price to pay for perfection.
