Print Los Angeles County is seeing new signs of a resurgent economy, with plummeting coronavirus cases allowing for a faster-than-expected reopening of bars and expanded capacity for restaurants and other businesses. In progressing Tuesday to the least restrictive yellow tier of California’s color-coded reopening system, the nation’s most populous county can now unshackle its economy to the widest extent possible, sparking hope for significant recovery in sectors long battered by the pandemic. A swath of businesses and venues — including restaurants, gyms, movie theaters, amusement parks, stadiums and museums — will be able to operate at higher capacity starting later this week. Indoor bars will be able to reopen without being required to serve food.
