sign that you will encounter driving up Charles Street
. It sits above the Korean
restaurant, Nu No Daji at the corner of Charles and 25th.
The mystery behind the message is solved as you continue down Charles Street around to the side of the sign (in neon letters on a curved brick face) to see the word All before the message, previously obscured by the wall.
PS ... Fun thing to do when showing friends around the city is to drive up Charles Street (making sure nobody is behind you), and suddenly SLAM on the brakes and point up to the sign screaming "YOU CAN EAT SUSHI!!!".
.... Make sure your back seat is ScotchguardedTM.
