Coffee and baked goods have always gone together, like rock 'n' roll, yin and yang, and bald-eagle hatchlings and William Howard Taft's toupee. Introduce your mouth to a dazzling duet with today's Groupon: for $4, you get $8 worth of coffee, sandwiches, and café fare at The Java Train in Butler.

The baristas at The Java Train brew up chalices of soul-bolstering coffee and prepare a menu of edible sidekicks, including pastries, sandwiches, homemade soups, and ice cream. Espresso, which has been scientifically proven to increase energy levels and the frequency of foam mustaches, awakens morning senses in a bevy of incarnations, such as cappuccinos, café mochas, or lattes ($2.99 for a 12 oz.; $3.79 for a 16 oz.). Breakfast sandwiches ($3.99 each) layer meat, eggs, and cheese on english muffins or bagels to muffle morning stomach grumbles, and signature sandwich creations ($6.95 each), such as the Roundhouse—a succulent amalgamation of horseradish-slathered roast beef, avocado, and red pepper bookended by tomato-herb focaccia bread, fulfill lunch quotas during midafternoon breaks. Conclude coffee conversations and food-based meals with scoops of ice cream in a cup or cone ($1.59 for a single; $2.29 for a double). The Java Train provides free WiFi for computer-equipped patrons to enjoy between sips, chews, and caffeine-induced yodels.
