Cosmo's Deli: A Charleston Institution for Sandwiches and Greek Food

What Cosmo's Deli Offers

Cosmo's Deli is a family-run sandwich shop in Charleston that has been serving the same menu of Greek and Italian sandwiches, salads, and sides since 1978. The deli is known for hand-sliced meats, fresh bread, and portions large enough to share. You can order at the counter and eat at one of a handful of tables inside, or take your order to go.

The menu centers on sandwiches built to order. The most popular are the Italian cold cuts (mortadella, capicola, salami), the roast beef, and the meatball sub. Cosmo's also makes Greek salads with feta and olives, spinach pie, and a small selection of sides like Greek potatoes and dolmas. Most sandwiches come on a choice of white or wheat bread and cost between $8 and $12.

Key Takeaways

• Cosmo's has operated continuously since 1978 and is one of Charleston's oldest independent delis.
• Sandwiches are made to order with hand-sliced meats and come in Italian, Greek, and American styles.
• The deli is small with limited seating, so takeout is a common option for lunch crowds.
• Cash and card are both accepted, and the deli is closed on Sundays.

Location and Hours

Cosmo's Deli is located on King Street in downtown Charleston, within walking distance of the Historic District. The storefront is modest—easy to miss if you are not looking for it—but the location puts it near shops, galleries, and other restaurants.

The deli is open Monday through Saturday, 10:30 a.m. to 6 p.m. It closes on Sundays. Hours can shift seasonally or for holidays, so calling ahead during off-peak times is wise if you are making a special trip.

The Sandwich Menu

The Italian sub is the signature order: layers of mortadella, capicola, and salami with lettuce, tomato, onion, and oil and vinegar. The roast beef sandwich comes with the same vegetables and a choice of cheese. Both are built fresh when you order and wrapped to go.

The meatball sub is made with house-made meatballs in red sauce and melted cheese. Vegetarian options include a feta and olive sandwich and the spinach pie, which is a baked phyllo pastry filled with spinach and cheese. Most sandwiches are sized for one person, though portions are generous enough that some customers split them.

Greek and Mediterranean Sides

Beyond sandwiches, Cosmo's offers a small menu of Greek and Mediterranean dishes that reflect the owner's heritage. The Greek salad comes with tomato, cucumber, red onion, Kalamata olives, and feta cheese. Greek potatoes are roasted with lemon and oregano. Dolmas (grape leaves stuffed with rice and herbs) are available by the piece or in small containers.

These sides work well as a light lunch on their own or as an addition to a sandwich order. Prices for sides range from $3 to $8 depending on the item and portion size.

Atmosphere and Seating

Cosmo's is a working deli, not a destination restaurant. The space is tight—a counter for ordering, a small refrigerated case, and four or five tables squeezed into the remaining room. The walls are decorated simply, and the focus is on the food and the speed of service rather than ambiance.

During lunch hours (noon to 1:30 p.m.), the deli fills up quickly with office workers and tourists. If you want to eat in, arriving before 11:45 a.m. or after 1:45 p.m. gives you a better chance of finding a seat. Takeout is the practical choice during peak times.

Payment and Ordering

Cosmo's accepts both cash and card. There is no online ordering or delivery through third-party apps—you order in person or by phone. Calling ahead during busy lunch hours can speed up your order, especially if you want a specific sandwich or side.

The staff works quickly and will ask how you want your sandwich built: which bread, which cheese if any, and which toppings. If you are unsure, the staff can recommend the most popular combinations or suggest something based on what you like.

Why Cosmo's Matters in Charleston

Cosmo's Deli is one of the few independent delis left in Charleston's downtown core. It has survived decades of neighborhood change, chain restaurant expansion, and shifting food trends by staying true to a simple formula: quality ingredients, made fresh, at a fair price. The deli is a gathering place for regulars who have been eating there for years, and a discovery for visitors looking for authentic local food beyond the tourist restaurant circuit.

The owner's Greek heritage is visible in the menu and the way the deli is run—family-owned, no shortcuts, and a genuine welcome to anyone who walks through the door. In a city where many old businesses have been replaced by chains or upscale concepts, Cosmo's represents a piece of Charleston's working-class food culture.

Frequently Asked Questions

Can I order online or through a delivery app?

No. Cosmo's does not have an online ordering system or partnership with delivery services. You can call ahead to place an order for pickup, or order in person at the counter.

Is there parking nearby?

Street parking is available on King Street and the surrounding blocks, though it can be competitive during lunch hours. A paid parking garage is one block away if street parking is full.

Does Cosmo's have vegetarian options?

Yes. The feta and olive sandwich, spinach pie, and Greek salad are all vegetarian. You can also order a cheese sandwich or ask the staff to build a custom vegetable sandwich.

How big are the sandwiches?

Sandwiches are sized for one person but are quite full. Many customers find them filling enough for lunch with leftovers, or shareable as part of a group meal. The staff can tell you which sandwiches are the heartiest if you want to know before ordering.

What is the best time to visit if I want to avoid crowds?

Early morning (10:30 a.m. to 11:30 a.m.) and mid-afternoon (2 p.m. to 5 p.m.) are quieter. The lunch rush runs from noon to 1:30 p.m., and the deli can have a line out the door during that window.
