"Hot Shoppes" were a restaurant chain that was popular in the Washington D.C. area. "Hot Shoppes" are gone now, but their parent company went on to become the Mariott Corporation of hotel fame.

There is a "Mariott Hot Shoppes Cookbook" that is sometimes available used on Amazon or E-Bay or at other used book sellers' websites.

There is a "Friends of the Mighty Mo and Hot Shoppes" Facebook page here: Friends of the Mighty Mo and Hot Shoppes
