I don't know if this is Top 5 all-time, but this is my Top 5 from the last year or so (call it "year and change"):
#5 - Pancho and Lefty's - Hare, TX
This is a place that
Bushie took me to on my last visit to the Austin/Round Rock area. We drove 45 minutes from Round Rock to this place - and the payoff at the end was worth it. I had mine with hand-cut potato chips (that might have needed some slightly hotter oil - or more time in the fryer, but they were good. You can (kinda) see Bushie's fries in the background - hand-cut, as well. If you're city folk like me, you might want to take Bushie with you so the biker denizens don't rough you up!
#4 - Runyon's - East Meadow, NY
This is a tavern/sports bar just up the road from the Nassau Coliseum/Hofstra University on Hempstead Turnpike. The burger was fantastic - the fries were ordinary.
#3 - Ranchman's Cafe (Ponder Steakhouse) - Ponder, TX
Of all the people who have incredibly large lists in the[url='http://www.roadfood.com/forums/topic.asp?TOPIC_ID=2976']These are the places I visited on Roadfood[/url] thread, few can claim this one. See the fresh-cut fries again - and let me assure you, that burger was a steak not long before I ordered it.
#2 - Kincaid's - Fort Worth, TX
This made a lot of other people's Top 5, too. Excellent burger, friendly staff, cheap, cheap pricing.
#1 - Peter Luger Steak House - Great Neck/Brooklyn, NY
OK...I know that people always say "in no particular order..." - well, the others may be in no particular order, but this is far and away the best hamburger I have ever had in a restaurant. I discussed why in the thread on [url='http://www.roadfood.com/forums/topic.asp?TOPIC_ID=24988']steakhouse burgers[/url].
Well, not too geographically diverse. But, Texas is a big burger place and I get their frequently. New York (especially the City) has its own burger culture, too. Still...I'd say that's a solid Top 5.
