Interesting, it appears parklets have to procure special events permits, because it blocks a sidewalk/street. In the Special Event Committee August 11 meeting agenda, which grants event permits, there is an application for a parklet from September 5 to December 31, 2015, on Martin Street in front of Craft. There's no link for the parklet itself but I contacted Craft to get more info and will pass it on when I hear from them.

The other parklet, on Roff Street, does have a link, and quite a bit of information on the parklet, though you will have to read some of the pages in the pdf sideways. A properly-rotated rendering can be found below.

A parklet is a sidewalk extension that provides more space and amenities for people using the street. Usually parklets are installed on parking lanes and use several parking spaces. Parklets typically extend out from the sidewalk at the level of the sidewalk to the width of the adjacent parking space. They are gaining popularity as a trend.

Parklets are new concept to Reno, but are used quite extensively in San Francisco. Here's a great map of all the parklets in San Francisco.

Seattle's Dept of Transportation created a great infographic from public and business surveys on parklets, and also have a map of parklets in the city.

On the flip side, here's an interesting article that our city council members and planners may want to read, to avoid a similar fate for any attempt at a parklet program. It details Oakland's failed first attempt at a program and how its parklet program was recharged. San Francisco suffered a similar hiccup and made necessary revisions to code to ensure parklets are properly maintained and don't become neighborhood nuisances. I'm not sure if there's currently any city code applicable to parklets, but if there's not, it's something to look at.
