In college I was on the Cycling Team (wouldn't know it by looking at me now

) and we always chose locally owned businesses to hold our gatherings.
Even as cheap college students we made an impression on that local business with our wallets. Made it a lot easier when we needed sponsors or donation for our races and events. As the club looks at possibly organizing TLCA event sponsorship will play a big part. If all the Human Bean locations are under one ownership they might be better potential sponsor than a one off local coffeeshop. No personal experience with how Starbucks handles local sponsorships.
With regards to recruiting new members (like myself) good drive by traffic is key. McCarran and Virginia locations likely get the most drive by Traffic.
Human Bean on McCarran/Langley and Pianissimo Coffee (if park up by Napa Sonoma/Chevron) facing Virginia will likely get the most eyeballs out of the locally owned business listed above. Both options have additional local businesses that would be potential sponsors.
I'm the FNG and haven't even paid my dues yet but I don't mind going by Pianissimo Coffee and testing the waters for March 20 gathering. I picked this option because the reviews mentions the owners having regular presence. I've been by the Human Bean several times and usually just young kids working.
