This place is a hidden gem inside the Rio! I came here for a post work celebratory drink with some colleagues and I absolutely adored the flight options. I ordered the champagne flight and it was really wonderful trying multiple types of champagne and exploring types I probably wouldn't have ordered otherwise. They also have a heavy pour ;)
The only draw back is there really isn't any food options besides bread and cheese (which they didn't offer, we had to ask for it). Unfortunately the bread we did order was below average and cold, not much of a compliment to our flight selections.
