I usually go to Mel's Coffee located next to the food court instead of the other drink places in the West Covina Plaza. I love their iced blended chai and the white chocolate chiller. They also offer boba drinks and a variety of hot and cold coffee drinks. Service is friendly and prices comparable to what you see at Starbucks and Coffee Bean & Tea Leaf. There's also tv screens around which is convenient if you wanna catch an NFL game. Make sure to pick up a flyer from the Plaza concierge desk. Usually I see a Mel's Coffee coupon on it!
