A major Hemming Park overhaul involving the investment of hundreds of thousands of dollars will commercialize the downtown gathering place by adding a restaurant and bar and a new stage area.Friends of Hemming Park CEO Vince Cavin said Thursday his group is prepared to spend about $85,000 to turn cargo containers into a bar and restaurant facility that will be located on the southeast corner of Hemming Park at Laura and Monroe streets. Planning also is underway to build a permanent 50-foot-by-50-foot stage at the west end of the park under the Skyway people mover.The recycling of cargo containers by converting them into buildings is a hot trend. The restaurant and bar would be created by linking two of those structures into an āLā shape and be run by the ownership that operates Black Sheep Restaurant in Riverside, Cavin said.
