Hungry Alberta hoppers are faced with a tough choice at the intersection of Northeast 27th Avenue: La Sirenita or La Bonita? Two of the city's most popular Mexican cafes are within a tamale's toss of one another. If you crave a California burrito, hit the former. For anything else (or for considerably less grease), La Bonita is damn near impossible to beat. Chicken enchiladas ($8.95) melt in the mouth and come swimming in a lake of green or red sauce with beans, rice and guacamole. Tacos ($2 and up) are loaded with everything from crispy carnitas to fleshy fish and some of the best slow-roasted lengua in town. Step in line (it's worth the typical 10-minute wait, which grows exponentially during Last Thursday) and get ready for some of the best, most authentic Mexican food in town.
