Well, we have the best sub thread.... and yes, I did a search for about 14 variations of "best" and "hamburger" (including abbreviations) and got a blank search result every time.... so how about a best burgers thread!
Small family places as well as major chains count here, so everything from the guy on the corner of 7th ave and center st downtown that's there hell or high water, all the way up to McD's (if you don't vomit after eating one of their burgers).
For me, I would have to say that the best burgers I've EVER had are a close tie between a Peter's Drive-In double cheeseburger or the Inglewood Cafe's "The Inglewood." (for those wondering, this place is a TINY little building that's at the corner of the block one street north of 9th ave crossing the zoo bridge, incidentally in *gasp* INGLEWOOD O_O)
Alas, since going semi-health nut, I can't enjoy burgers as much anymore, so post away with your favorite places and burgers
