Cold Coffee without Ice Cream Recipe - Summer recipe - Cooler Recipe

As mentioned in my Chocolate mocha breakfast shake post, these days I do take coffee once or twice a week. When I was having tooth pain my doctor advised not to take any hot beverages. When I first came to SG and in my first job, my boss brought me to Spinelli. When I was browsing thro' the menu I saw this cold coffee and out of my curiousity I ordered it. I preferred hot one to cold one. After that I tasted this cold coffee a couple of times only. After that I tried it only recently and I kind of liked it. May be I am more open to different food as food blogger   .. Whatever be it I am enjoying more options of food
