Restaurants In Downtown Miami

Any suggestions on things to do in Miami Florida for ages 20-21, during the weekend of August 9-13?
A couple of friends and I are going to Miami, for a short vacation before school begins again…Any suggestions on reasonably priced hotels, restaurants, flights from STL, clubs, activities, etc. We are open minded and just want to have a chill time on a budget. We went to West Palm, FL for spring break and drove to Miami for a day but didn’t get to explore like we wanted… We are aiming to stay downtown/near Ocean Drive.
Yeah drive down to the Florida Keys. A great place to go and eat.
