My earnest waiter stays attentive and polite, even on a summery day when the sidewalk tables fill at noon with hungry diners and you can hear the roar of the first pitch at Fenway a few blocks away. No Belgian waffles on weekdays. 975-0075 Breakfast is served from 8 a.m. until closing at this Coolidge Corner deli, and there is enough variety that you could eat here from Mother's Day to Father's Day without repeating a dish. There are granola or buttermilk pancakes, potato pancakes with applesauce and sour cream, or cheese blintzes. You can always count on bagels with lox and cream cheese, fried matzo, or corned-beef hash and eggs.
Diners look and sound as if they are in their own home.
Those who really prefer to eat at home can stop by for takeout. The partitioned booths, banquette seating, yellow tin ceiling, and wooden floor give off a cheerful vibe. Someone's singing the blues.
