Yes: It sound as if you are experiencing gastric irritation. This may be do to peptic ulcer disease or to gastroesophogeal reflux disease. Often peptic ulcer disease will result in pain of the mid-portion area of the back area. There is no associated radiation of that pain into the legs.

Yes or gallbladder: This could be a stomach or gastrointestinal issue ranging from stomach or gastric irritation known as gastritis to a stomach or gastric ulcer or heartburn known as reflux(gastrointrstinal) or a possible gallbladder problem as the symptoms occur only with eating and with a particular type of food. A typical back problem would not be affected by eating, especially by a particular food type.
