There is no 'bottle service' or any other such nonsense. First off, some basics: The Piazza Lounge is not a 'club' like you see in the big Strip casinos.
The singers and bands were so different, and the scenes so distinct, that I thought I should give you a guide for your visit. On a recent trip to Vegas I ended up at this fun lounge for three nights straight.
Thursday's young jazz singer tried so hard to be 'hip', but it didn't work for me. Tuesday was next, with a promising young singer and a tight, professional band. Wednesday gets the biggest crowd and was by far the most happening scene.
