I recently found the best burger place on the east coast.
It is Five Guys.
The meat is fresh-ground. The patties hand-formed and made to order. The bun is soft but not too soft. You choose any [or all] of the extensive list of toppings for free [except cheese which is extra]. I added ketchup, onion, lettuce, tomato, jalapenos. There are mushrooms on the list too. [Sorry, AJ, there are no beets.]
It is by far – the. best. burger. I. have. ever. eaten. [And the fries are to die for too. Fried in pure peanut oil.]
