Unfortunately my psychic abilities don't seem to work over the internet... perhaps you can at least give us some pointers as to what sort of activities you like so we don't send you off visiting temples / traipsing round shopping centres / whizzing through museums / checking out the wildlife (both daytime and/or nighttime) etc when you actually want to be doing something else!
As for cheap food options near your hotel, there's the food court in the KLCC mall as well as mid-range restaurants on one of the higher floors (Madame Kwan's; Little Penang Cafe).
