You come in because you see they've got chorizo there, and then you're surprised by how many different types there are available. Then you go "oh, they've got empanadas - I'll grab one to go" and when you eat it, you'll be happy you got it.
But you probably didn't realize how much you missed here. Did you notice the great marbling and ageing on the steaks (although can be South American cuts, so not that familiar looking)? Did you consider the other non-empanada hot table items?
It's easy to pass over this place, but it's worth to give it that second look to realize there's lots of quality here at a reasonable price - just like the rest of Kensington Market.
