No wifi limits, no wifi password. Network name is Filter Cafe. Tons of space to chill: sofas are abundant, plenty of tables and excellent lighting. Menu is huge, big selection of pastries, and an excellently pulled espresso. Great spot to crank out some work or chill with friends on a sofa. Great tunes, too. PrintWithMe available here.
WiFi latency here is very good and consistent. I was able to have an HD video meeting with a co-worker from here that worked great, even though the speed is slow. The noise level here is relatively quiet, especially for how packed it is. Tons of laptops and headphones, and most people here having personal convos are trying to whisper so everyone around them doesn't hear.
They charge you extra to use a card, but they'll keep your card at front like a tab, so you can order coffee and food over a period of time and pay at the end to get above $10 min.
