A new bar menu from Flemming's, Pizza Hut looks to take a slice of the sandwich segment, a new prototype for Souper Salad and several chains open new locations mark this week's Chain Operating Report.

Dunkin' Donuts signed a multi-store development agreement with new franchisees Buzz and Brad Calkins for 12 new restaurants in Denver. The plan calls for the first restaurant to open in 2013 and the remainder by 2018.

Fleming's Prime Steakhouse & Wine Bar is rolling out a Bar la Carte Menu. Served exclusively in the bar, the new menu is available any time and includes items that are more substantial than traditional appetizers that come in larger portions. Fleming's Bar a la Cart Menu includes: salt and pepper shrimp, Prime Steakhouse meatballs, Fleming's Original Prime Rib Melt, filet mignon flatbread, cedar-roasted mushroom and artichoke flatbread, house-made Burrata, and a prime burger. Fleming's created the menu so each item shares well and pairs with a variety of cocktails, wines and beers.

Granite City Food & Brewery Ltd. (NASDAQ: GCFB) purchased the assets of the Cadillac Ranch All American Bar & Grill in Pittsburgh, Pa., for approximately $0.9 million.
