Our party of four met at Houston's for a late lunch this week.  The service was excellent and the food was very good, though over priced ($14 for a small plate of veggies? ), but we all left with the same complaint, \""Why do they play such loud music?!\""   We could barely hear each other despite the fact that the restaurant was nearly empty.    The ambiance of Houston's seemed to conflict with loud music overhead -- I won't be back, even if eating alone.
