Will i gain weight today?

i ate at uno's- an 8 0z surloin steak, steame broccoli, two cups of coffe (with one little skim milk and equal sugar in each), boiled vegetables, very high calorie ice cream (containing whip cream, fudge, oreos, among other things) and a bunch of frosted flakes, maybe even half a box. i NEVER eat thi much. im only less than 110 pounds and 5'5., will i gain weight?
