First, you need to locate the Las Olas Centre on Las Olas Blvd. (Hint: It's across from the Bank of America Bldg.) . It's a prestigous office building. Come inside to the lobby.
You will see to your left a security guard station. Just ask the guard, "where the heck is Bob & Wilson's, there are no signs?". He'll help you find us.
Or, if you want to go it alone, look for the door next to the elevator. Go through the door.
