Despite all the development in the Reston-Herndon area over the past several years, conspicuously absent was a restaurant that consistently served good submarine sandwiches. To fill that void, Subway sub shop opened in the Fox Mill shopping center early this summer.

Small and primarily a carryout, the Subway offers 19 different subs in either six-inch or foot-long sizes. They range in price from $1.09 for the six-inch vegetarian sub to $6.79 for a foot-long king crab sub.

The sandwiches look so tempting there is a tendency to order the large one, which means there is usually some left over for lunch the next day.

On a recent visit, my wife, 11-year-old and 9-year-old sons and a 12-year-old friend decided to eat in the shop instead of taking the sandwiches home. Although there are few tables, there are two reasons why space is usually available for dining in the shop: the Subway features quick service and most people carry their food out.

The five of us placed a variety of orders at the counter, waited about five minutes for them to be filled, and returned to our table laden with sandwiches, soft drinks (small for 45 cents, medium for 55 cents and large for 69 cents) and several small bags of chips (35 cents each).

The subs were served on soft rolls brimming with our carefully selected ingredients. There are up to 16 garnishes available for your sandwich, including American or provolone cheese, onions, lettuce, dill pickles, tomatoes, green peppers, hot peppers and black olives. Regardless of how many you choose, the price remains the same.

My wife ordered a full foot of Subway Special (ham, Genoa salami and bologna, $2.99) loaded with everything except onions. The meat was lean and sliced very thin, making for a generous and tasty sandwich. It was so large she couldn't eat it all, so I gallantly finished it.

No such luck with my sons. The older one finished a 12-inch roast beef sandwich ($3.39) overflowing with garnishes. My younger son could not finish a slightly less filled model of the foot-long roast beef sub, but he spirited the remains away for lunch the next day.

The boys' 12-year-old friend had, in my estimation, the evening's best sandwich. Called the BMT (for "biggest, meatiest, tastiest," according to the menu), it was 12 inches of ham, pepperoni, Genoa salami and bologna and cost $3.39. Appropriately loaded with extra ingredients, it proved too much for him to finish.

I had a half-foot of steak and cheese for $3.39, a price that included double the regular amount of steak. The sandwich with the regular portion of steak is a dollar less. (The extra-meat option meat is available on every sandwich at the Subway.) I had the sub with about half the available garnishes and found it tasty and filling.

We passed up desserts, which consist of two choices: packaged double chocolate cake or carrot cake, each 69 cents.

A nice option (though we didn't choose it) is that virtually any sandwich can be ordered as a salad; the bread is replaced with lettuce and any other garnishes a customer orders. The price is the same for salad or sandwich.

The total tab for five (no tip necessary) was $22.03.
