Until now, if you wanted to enjoy one of M Burger’s quickly griddled burgers, you had to find one attached to an older, more expensive Lettuce Entertain You restaurant in River North — specifically, your options were tied to Tru and Osteria Via Stato. But M Burger is breaking free, as its third location opens today in the Thompson Center’s Atrium Mall. For the past two days, crowds have flocked to the location for practice runs, with official reports claiming that over 400 people lined up each day.
M Burger’s menu is purposefully short — though a couple formerly secret sandwiches did finally get billing last month — so don’t expect any new items. However, this specific location will be offering a Shake Break promotion, where all shakes will be half-priced everyday from 2 p.m. to close. Not bad.
The Thompson Center M Burger will be open Monday through Friday, from 10 a.m. to 5 p.m.
M Burger, Thompson Center, 100 W. Randolph, Chicago, IL 60601-3219; 312-578-1478
