Tijuana – Construction workers are still removing debris and gardeners are tending to recently planted lawns, but a new kind of betting has begun at the iconic Caliente casino. The historic building has a new facade with a Las Vegas-style entryway. Within, there's the greyhound track, remodeled halls for traditional bingo games, sports betting, an international-cuisine restaurant and a piano bar. Also inside are 1,333 new electronic gambling machines, which turned Caliente into the largest casino in Mexico when it opened last month.
