Another contender has emerged in Portland's unofficial quest to create the city's best burger: Killer Burger will open sometime later this month in the NE Sandy space that formerly housed Nasca Peruvian Restaurant. Owners/chefs Mark McCrary and TJ Southard promise menu offerings like the "Peanut-Butter-Pickle-Bacon-Burger" and something referred to on their Facebook page as a "grease burger."
