Gaining experience before you hit the majors can be invaluable, except in the case of Henry Rowengartner, whose incredible arm strength made him an instant star, and Gary Busey nail his mom. Finally getting called up to the big leagues, Fenway Cantina, opening Wednesday.From experienced owners who've mostly cut their resto teeth in the 'burbs (88 Wharf, Blue on Highland, etc), FC is a 150-seat split level Tex Mex-ery set in the shadow of Fenway, fully revamping the former Chicken Bone w/ hand rolled copper light fixtures, album covers, light zebrawood laminate booths, one of Boston's few tabletop shuffleboards, and a 25-seat oak bar shaped like a 7, or is it an L, loser? The fare goes both Tex (a Bourbon BBQ slathered mesquite sirloin piled w/ crispy fries, Lone Star-styled chili) as well as Mex with fish tacos/quesadillas/fajitas, chimichurri–sauced carne asada, and a chile relleno that's stuffed then roasted, though mercifully not by Jeffrey Ross. For snacking and small bites, FC serves up fresh popcorn sprinkled with habanero salt, salsa verde-doused corn & poblano tamales, and Texas pork "wings" in a chili BBQ sauce blended with mango, although they've managed to strain out the tight, lame shorts and unidentifiable Latin accent. If you're coming in to celebrate/bitch post-game, there're 20 draughts on tap (Green Monsta, Pretty Things, Cisco), 65+ bottles (Fisherman's Ale, Rogue Dead Guy, 21st Amendment Watermelon), and a limited selection of big margarita/hurricane style cocktails -- just don't go overboard, or you might find yourself on the receiving end of some funky butt lovin'.
