Good luck biting into that fat burger, big-mouth! Just pour on the Heinz 57 and try your fork. Estonia's elaborate take on the all-American restaurant, BabyBack is an oasis of vinyl booths, 1950s ads and truck-stop kitsch where diners chow down on burgers and pizzas to the sounds of country music. The speciality, of course, is barbecued pork ribs and there are a few kinds to bite into. Not a place for dainty dining.
