What would I do without Green Grotto? During the day it's great for working with ample seating and plugs, good natural light and just enough background noise. After 7pm (Friday to Sunday), it's a lively place with groups playing board games, uproarious laughter and the occasional couple on a date, although I don't know how they carry on above the din.
The drinks are alright. They're of the blended powder/syrup/sugar/food colouring variety and you can half sweet this or no syrup that, but your drink still won't be healthy...or all that great. Unless you're a teenager then the drinks are UH-mazing!
Come to work, stay for the outlets/wifi, order drinks to pay cover charge and don't be obnoxious or the staff will enforce their 3 hours sitting rule.
