One noted feature of the Epicurious Burger was that the patty, which is of regular size comes with buns that are smaller than average. Small bread make the patties look bigger?
The patty, apart from being better marinated is probably just a little better than those from Botak Jones which is along the same standards as wham!burger. Which means that it's visually more impressive than it is tasty. If you like them heftier and firm, this is definitely not the burger. There are better options as I can recall from the likes of Wild Rocket, Brewerkz, or Marmalade Pantry instead. This patty in this one is just good for epicurios-ity, not much more.
