Best burgers in the STL

O'Connell's

Ground Sirloin with cheese
$5.75

I'd heard good things about O'Connell's, so I decided to give it a shot. This burger is simple, with a chunk of beef covered in American cheese. It was filling, but I'd rank it near the bottom of all of four burgers I'd tried to this point. However, for a mere $5.75, it was a pretty good buy. Honestly, I'd say my experience could be summed up by this comment from a Metromix reader.
