it was definitely better maxs burger, they don't have jalapenos, no mushrooms and they don't have tabasco hot sauce or A1 for the burger If I return to this place I will bring you a bar of soap to wash your aprons, it seems that you mop the floor with them super filthy.
My new favorite burger place. The juiciest burgers by far. So much so I need to stop eating where the drippings are now embedded onto my carpet. I give myself one star for being a sloppy eater but definitely five stars for a good burger.
When I walked in I was immediately impressed with the cleanliness and aroma. When I tell you the burger was delicious that just does not do it justice. The juiciest most flavorful burger I've had in years. Dating back to the days of grandfather's backyard BBQ. The bun was toasted perfectly which added to the overall experience. An 11 out of 10. Will be going back soon. My compliments to the chef.
