A no-nonsense, hold-the-health-food house of heartiness. Regulars know to bypass the printed menu and just ask Gretchen what she's got on the stove or in the fridge. Whatever you do, don't forget to order two scoops of her special, cholesterol-laden shrimp, tuna or chicken salad on the side ($2.75-$3.25 each). Or try the true-to-its-name Mondo Meatloaf sandwich ($6.75) and skip the sides (not to mention the rest of your workday�nighty night!).(JD)
