The most adventurous thing diners will find at Johnny B's are the bright-green tennis balls capping the legs of the chairs. Aside from that, everything here is strict greasy-spoon fare. The menu actually has more meat choices (ham, bacon, sausage links, corned beef, German sausage, etc.) than it does veggie choices for its omelettes (green peppers, onions, mushrooms, tomatoes, no etc.). So it's best to just give up your whole health kick and go for the regular specials board, which features one of those meats with golden crisp hash browns, two eggs and toast (also absurdly golden) for between $5.25 and $5.95. Or get there before 8 to eavesdrop on old-timers telling war stories and to catch a decent early-bird special ($3.50). (MB)
