Menu options and how ordering works

Firehouse Subs operates on a build-your-own model. You start by selecting a bread type—typically Italian, wheat, or a specialty option—then choose your protein. Hot sandwiches might include meatball, Italian meats, or chicken options, while cold sandwiches feature turkey, roast beef, ham, or vegetarian proteins. Once you've chosen your base, you add vegetables like lettuce, tomato, onion, and peppers, then select sauces and condiments.

The ordering counter moves efficiently, and staff can suggest combinations if you're unsure. Because you're building as you order, the sandwich is made fresh to your specifications. Sides typically include chips, a pickle spear, or a small salad, and you choose a drink size to complete your order.

Location and parking in downtown Greenville

The restaurant sits at 1 North Main Street, placing it in the heart of Greenville's downtown Mill district. This location puts Firehouse Subs near the Reedy River, Falls Park, and other downtown shops and offices. If you're working or visiting nearby, the restaurant is walkable from most downtown spots.

Parking in downtown Greenville operates through a combination of street parking, public lots, and private decks. The Marketplace at the Mill complex has its own parking areas, though availability varies by time of day. Street parking along Main Street and nearby blocks is also available, though it may be limited during peak lunch hours. If you're unfamiliar with downtown parking, arriving slightly before or after the noon rush typically makes finding a spot easier.

Pricing and what to expect for your meal

Firehouse Subs prices sandwiches in the mid-range for fast-casual dining. A single sandwich with a side and drink typically costs between $10 and $15, depending on your protein choice and any premium add-ons. Combo meals bundle the sandwich, side, and drink together, which is usually the most economical way to order.

The restaurant accepts cash and card payments. Because this is a build-your-own format, you pay at the counter after your sandwich is made, not before. If you're on a tight lunch break, the ordering and preparation process typically takes 5 to 10 minutes during slower periods, though it may take longer during peak lunch hours between 11:30 a.m. and 1 p.m.

Why Firehouse Subs appeals to downtown workers and visitors

The customization model appeals to people with specific preferences or dietary needs. Because you're choosing each component, you can avoid ingredients you don't want, adjust portions, or create combinations that suit your taste. This flexibility makes it easier to find something that works whether you're vegetarian, prefer less mayo, or want extra vegetables.

The downtown location also matters. For people working in the Mill district or nearby offices, Firehouse Subs offers a quick lunch option without leaving the area. The restaurant fits into Greenville's broader downtown dining scene, which has expanded significantly over the past decade with new restaurants, cafes, and food options opening regularly.

Hours and how to plan your visit

Firehouse Subs Marketplace at the Mill operates during typical lunch and dinner hours, though specific hours vary by season and day of the week. Most locations open around 10 or 11 a.m. and close in the evening, with slightly shorter hours on weekends. Before your first visit, checking their current hours online or calling ahead ensures you don't arrive to find the restaurant closed.

The lunch rush—roughly 11:30 a.m. to 1 p.m.—is the busiest time. If you prefer a shorter wait, visiting slightly before or after this window usually means faster service. The restaurant is also accessible for dinner if you're downtown in the evening and want a sandwich rather than a full sit-down meal.

Frequently Asked Questions

Can I order online or do I have to order in person?

Most Firehouse Subs locations accept online orders through their website or app, though availability varies by location. Contact the Marketplace at the Mill location directly to confirm whether online ordering is available there, as some locations may operate differently.

Are there vegetarian sandwich options?

Yes. You can build a vegetarian sandwich by choosing a bread, selecting vegetable-based proteins or skipping protein entirely, and adding vegetables and sauces. Ask the staff what vegetarian proteins they have available, as options may include veggie patties or other plant-based choices.

What's the difference between hot and cold sandwiches?

Hot sandwiches are pressed or toasted after assembly, warming the bread and melting any cheese. Cold sandwiches are served at room temperature without toasting. Hot sandwiches typically feature heartier proteins like meatballs or Italian meats, while cold options include turkey, roast beef, and ham.

Is there seating inside the restaurant?

Yes, Firehouse Subs has indoor seating. The space is part of the Marketplace at the Mill complex, so you can eat in the restaurant or take your sandwich elsewhere in the building or downtown if you prefer.

Do they have options for people with food allergies?

Because you build your own sandwich, you have control over ingredients. Tell the staff about your allergies when ordering, and they can help you avoid specific items. However, cross-contamination is always a possibility in a food preparation environment, so discuss your specific concerns with staff before ordering.
