We spent 3 delightful nights at the Riverside Hotel. The room was large, clean, and nicely furnished. The bathroom was large, spotless, and well-equiped with lots of towels and toiletries (my only complaint was no shaving and/or make-up mirror). Try to get a room in the tower as the view over the New River is very nice.
We also ate one meal in the Grill Room-expensive but excellent and enjoyed breakfast sitting on Los Olas Boulvavard ( also expensive, but you pay for a great location). Overall, the Riverside is a very classy hotel in a very classy location and is to my knowledge the only hotel on East Los Olas which is often referred to as the "Rodeo Drive" of Fort Lauderdale.
