The first visitors to a casino about to open in downtown Cincinnati say they had a good time at a dry run of the facility but hope that a few kinks get worked out before visiting again. Hundreds of people who went to Wednesday's invite-only event at Horseshoe Casino Cincinnati posted their initial thoughts on social media. Some said it was difficult to get drinks, others reported long lines and some said a few dealers were making mistakes and moving slowly. Others praised the sleek look of the $400 million casino and the friendliness of the staff, while others bragged about winning money. If the Ohio Casino Control Commission finds there were no major problems during the dry run, the casino will open to the public on Monday.
