The new Umami-mini (U-Mini) location in Westwood goes into one of the most unloved restaurant spaces in the whole area.
They do a surprisingly nice job, with lots of outdoor seating, roughly 10 useless employees standing around doing little (for a self-order burger joint, why do you need so many people??), and an almost-too-easy-to-use-it's-confusing iPad ordering system.
Unfortunately the food is only average. The burgers are a little different than the regular Umami menu and lack the "ZOMG SPECIAL!" feel, the Umami fries are just regular fries with a bunch of special seasoning (as opposed to awesome square-cut blocks or whatnot), and the soda machine's CO2 carbonation was broken when we visited. Ack.
