BEST CHAIN COFFEEHOUSE

There is a secret to serving good coffee that goes beyond the beans, the roast, and the water. Here it is: temperature. And those comical, corporate Einstein Bros. have figured this out. So they start each pot with a blend of Central and South American beans, roasted to a light brown, and they brew the java with water that is between 190 and 205 degrees Fahrenheit. (For those who skipped middle-school science: The boiling point of water is 212 degrees F.) Then, when the coffee is made, specially calibrated heaters under each urn hold the coffee at 175 degrees. That's hot. Oh, and if the brothers' employees are paying attention to company directives, they are also brewing up fresh coffee at least every hour, even if that means dumping out a full 1.5-gallon urn, according to Ron Savelli, the chain's vice president of menu development. Of course bagels, sandwiches, and soups are also available. But the allure here is coffee. Hot and fresh, Mel's Neighborhood Blend is perfection.
