You’d expect to find a quaint and classic soda fountain and grill in any historic district. You wouldn’t expect to love it as much as locals love Sid’s. Maybe it’s the memories, or the food, or a little of both, but Sid’s Rainbow Grill, which inhabits both the location and the spirit of the original Rainbow Fountain, delivers on nostalgia and wholesomeness while serving up a mighty good burger. Its hours are limited, which makes it even more special when you do get to visit.
