First, you'll have to find the place. Multiple trips to the Musical Box, and you'll still walk up and down that one block of Avenue B, muttering to yourself, "Where the hell is it, again?" But persevere, and you'll eventually stumble across the unmarked door. Part the velvet curtains and step inside: The bar's on the left, and the pool table's in the back room, with well-worn couches you've sat in too many times to mention. Musical Box's outdoor patio is less patio, more tiny scrap of cement for every smoker in the bar to pack themselves into for most of the night.
