Before grinders were invented, coffee lovers would tie individual beans to railroad tracks in the hopes that passing baristas would rescue them and turn them into potent brewed concoctions. Get a less devious caffeine boost with today's Groupon: for $3, you get $6 worth of coffee and cafe fare at 6th Sense Cafe.

At 6th Sense Cafe, baristas pour a variety of hot and iced beverages, pairing the caffeinated drinks with a menu of assorted cafe sweets and savouries. Coffee devotees can fill cups and laminated pockets with regular ($1.70), large ($1.90), and super ($2.10) size helpings of the cafe's featured coffees, including a fair trade brew. Crunch on a veggie samosa ($1) or chew to a softer beat with blueberry, chocolate, and low fat raisin muffins ($2). To conjure a sweet crunch, patrons grab biscotti in flavours such as nutty espresso, plain almond, or dipped orange ($2), and then use the cookies to take depth readings of a sweet white cafe mocha ($3.25 small–$4.45 super).
