The Impossible Burger, a vegan patty produced in a Silicon Valley lab that oozes red like real beef, will make its Pacific Northwest debut at six Portland restaurants this weekend, according to a spokesperson for Impossible Foods.

The burger, made from a hemoglobin extracted from the roots of soybean plants, mimics the taste, texture and blood of a medium rare burger.

The meat-like product has already had some success, drawing in more than $250 million from investors and the backing of a handful of top chefs.

Here are the six Portland restaurants that will launch the Impossible Burger this weekend, all on the west side:

Headwaters

Imperial

Irving Street Kitchen

Jackrabbit

Paley's Place

SuperBite

Note: Most restaurants plan to roll out the Impossible Burger Saturday, but some, including Jackrabbit, have already put it on the menu, according to Impossible Foods. Check social media or call ahead to verify availability.

Update, 12:30 p.m.: According to Jackrabbit, they will begin serving a limited number of Impossible Burgers along with the other five restaurants on Saturday, not Friday, as previously announced by Impossible Foods.
