One of the three or four eateries that serve the sprawling medical/retail/professional campus of Greenspring Station, the Wine Merchant does a brisk lunchtime business. Fortunately, you never have to wait long for a sandwich--there are at least a half dozen guys working behind the counter during lunch rush. Use that time to browse for a cheap bottle of wine--we recently picked up a nice Malbec for less than $10. The specials board always has something worthy; on this visit, we grabbed an avalanche--roast beef, shredded Asiago, vinaigrette, tomato, and lettuce on a tasty, crusty ciabatta roll ($6.79)--but the powerhouse ($5.99), with turkey (or tuna), alfalfa sprouts, cucumber, tomato, lettuce, Muenster cheese, and pepper-Parmesan dressing on multi-grain bread has been the staple on other trips. Grab a bag of kettle chips, and if you're not going to drink that wine for lunch, a bottle of iced tea or something.
