I dunno, depends on what kind of things you like to do. Plenty of resteraunts and bars around here. (the kelvin Arms down in Rice villiage is especially good) Lots of art and culture museums around there. There is an air museum a few miles outside Houston, also the Battleship texas. Of couse my computer is also here, (The 13th wonder of the modern world, upstaged only of course by the cordless bagel slicer). If you bring the Mrs. Smasharoo, there is the shopping circut of course. Or you could go drive by the Bush Sr. residence and join the weekly mooning train.
There is a very nice aquarium/restaraunt in downtown Houston too.
Other than that, it really depends on what you are into.
