It's strictly first come, first serve at this compact spot in Bloomingdale just north of the Union Market district. Some order takeout at the touch screen, while others pull up a seat at the counter and order via QR code. It's all very straightforward, as is the menu with a narrow focus on spring and summer rolls, as well as impressive pho. Chef Hai Le has a background in butchering, perhaps best seen in signatures like the Butcher’s Choice with brisket, bone-in rib and beef shank, or The Works, with an array of different cuts topped with torched bone marrow. The broth is rich and savory, and while set bowls are always a good choice, the build-your-own option is equally appealing. Order a Vietnamese iced coffee or salted lime soda to go with these skillfully made offerings.
