I LOVE CBTL!!!!!
In my opinion, CBTL (particularly this location across from the UNLV campus) is superior to Starbucks. I frequent this location to study if I want to get out of the library. It is less crowded than Starbucks and there is a lot more space and more available tables.
Also, their WiFi is faster than Starbucks, their coffee/tea is cheaper (and generally tastier) and they have newly available FREE charging stations for all kinds of phones, including chargers that are already plugged in. Need a free charge? Stop by. Last night, they had chargers for iPhones, iPhone 5, Blackberry and one other that I didn't recognize. Also, they have a lot of power outlets!
CBTL is always clean their staff have always been very friendly. Although I can't speak for their coffee (I've just never ordered it), they have THE BEST selection of tea. Particularly, their English breakfast tea is delicious and tastes just like home.
