Marrow just opened this week in Uptown, it's located in the former Looney's BBQ space. Looks to be a direct competitor to Stag's Lunchette.
They had about 4 sandwiches (grilled cheese, asparagus, pastrami I think, patty melt), a salad, fries, strawberry shortcake and a few other things.
I ordered the patty melt and fries and am extremely pleased. The patty melt is delicious, not salty like I usually find them. The fries are thin, shoe-string-like, which are my favorite. I'm actually slightly hestiant to write about them because I don't want the lines to get long like at Stag's! But this place is a great find. I think it's even better than Stag's.
I did a quick internet search and the owner used to own a food truck called Jon's Street Eats. They butcher their own meat in-house and try to use all the parts.
