since my taco obsession really took hold back earlier this year, the taco joint that i've frequented the most has got to be tacos matamoros II, a tiny establishment on 5th ave in the south end of sunset park. they have another larger location (the original) thirteen blocks up fifth ave but this one seats about twenty-five & in my case, is perfect for jumping off the train at the 59th st N, walking up the hill, ducking in for less than ten minutes to get tacos & heading back down the hill to continue home.
