Tomorrow is the big kick-off day for Haven Gastropub and Brewery's new pop-up initiative: Haven Burger.
To celebrate this momentous occasion, the Pasadena eatery is offering free burgers to the first 100 people in line (limit one burger per customer).
They're calling the new burger pop-up a 'restaurant within a restaurant.'
Going along with the Haven's style of comfort cuisine, its new dining spot will offer a selection of grass range burgers like its lamb burger, house sauces and rotating burger specials.
