Diablo's Southwest Grill in South Carolina — What to Expect

A casual spot for Southwestern flavors and grilled specialties

Diablo's Southwest Grill brings Southwestern cooking to South Carolina with a focus on grilled meats, fresh ingredients, and bold spice levels you can control. The menu centers on items cooked over an open flame—carne asada, grilled chicken, and wood-fired preparations—paired with house-made salsas and traditional sides. The atmosphere is relaxed and family-friendly, with a bar that serves margaritas and regional beer selections. Portions are generous, and the kitchen will adjust heat levels to your preference, so you can order mild or bring the fire.

The restaurant operates as a casual counter-service or table-service hybrid depending on the location, meaning you can order at the counter and grab a seat, or sit down and order from a server. Prices fall in the mid-range for casual dining—entrees typically run between $12 and $18. The space usually includes both indoor seating and outdoor patio areas when weather permits.

What to order and how the menu is organized

The core menu divides into a few clear categories: grilled proteins (carne asada, pollo asado, grilled fish), build-your-own bowls and tacos, and combination plates that pair a protein with rice, beans, and tortillas. Most people start with chips and salsa while deciding—the salsa is made fresh and changes seasonally. Diablo's also offers chile-based sauces beyond salsa, so ask your server or the counter staff what's available that day.

Carne asada is the signature item—thin-sliced grilled beef marinated in citrus and spices, served with warm tortillas and lime. The pollo asado (grilled chicken) is leaner and works well for those watching portions. Combination plates come with your choice of protein, and you can add extras like guacamole, queso fresco, or additional sides for a small upcharge. Vegetarian options include grilled vegetables, black beans, and cheese-based dishes, though the menu leans toward meat.

Beverages include agua fresca (a light, fruit-based drink), Mexican sodas, beer, and margaritas. The margarita list usually includes house versions and premium tequila options. Non-drinkers will find iced tea, lemonade, and soft drinks.

Pricing and what to budget

Entrees typically range from $12 to $18 depending on protein choice and whether you add premium items like shrimp or extra guacamole. Combination plates—which include a protein, rice, beans, and tortillas—sit at the higher end of that range. Build-your-own bowls and tacos are usually $11 to $15. Appetizers like queso dip, ceviche, or chile rellenos run $6 to $9.

Sides and extras add up quickly: guacamole is usually $3 to $4, queso fresco or sour cream $1 to $2 each, and additional tortillas $1 to $2. Drinks range from $2 for soft drinks to $6 to $8 for margaritas. If you're dining with others and sharing appetizers, budget $20 to $30 per person for a full meal with a drink.

Atmosphere and seating

Diablo's locations typically feature a casual, open layout with bright colors—oranges, reds, and earth tones reflecting Southwestern design. The space is loud and lively, especially during lunch and dinner rushes, so it's not a quiet spot for a private conversation. Most locations have a bar area where you can watch the kitchen work, which adds to the energy.

Seating varies by location. Some have a mix of tables and booths; others are primarily tables. Outdoor patios, when available, are popular during warm months and offer a more relaxed vibe. The restaurant is generally accommodating to families with children, and high chairs are usually available. Noise levels and crowd size peak between 11:30 a.m. and 1 p.m. for lunch and 6 p.m. to 8 p.m. for dinner.

Dietary preferences and customization

The kitchen is accustomed to modifying orders. You can request no cilantro, extra lime, beans on the side, or rice swapped for vegetables. Spice levels are fully adjustable—order mild, medium, or hot, and the staff will prepare your dish accordingly. If you have a specific heat preference, mention it when ordering rather than after the food arrives.

Vegetarian diners have options: grilled vegetable plates, cheese enchiladas, bean-based dishes, and custom bowls with no meat. Gluten-free diners should ask about corn tortillas (usually available) and confirm that salsas and sauces don't contain gluten-based thickeners. The restaurant can usually accommodate these requests, but it's worth confirming at the time of order. Dairy-free options are possible if you skip cheese and sour cream and ask about oil-based preparations.

Hours, location, and parking

Diablo's Southwest Grill operates at multiple locations across South Carolina. Hours typically run 11 a.m. to 9 or 10 p.m. daily, though some locations may close earlier on Sundays or have extended hours on weekends. It's worth checking the specific location's hours before you go, as they can vary.

Parking depends on the location. Most standalone or strip-mall locations have dedicated parking lots. Urban locations may have street parking or shared lot access. Call ahead or check the restaurant's website or social media for the address and parking details of the location nearest you.

When to go and what to expect

Lunch (11:30 a.m. to 1:30 p.m.) is the busiest time, with lines at the counter and a wait for tables. If you want a quieter experience, go mid-afternoon (2 p.m. to 5 p.m.) or after 8:30 p.m. Dinner (6 p.m. to 8 p.m.) is moderately busy and is when the bar sees the most traffic. Weekends are busier than weekdays across all hours.

Counter service is faster than table service—you order, pay, and receive your food in 10 to 15 minutes. Table service takes longer, especially during peak times, so budget 30 to 45 minutes from order to plate. The restaurant does not take reservations at most locations, so expect to wait during busy periods or come at off-peak times.

Frequently Asked Questions

Do they have a kids menu?

Most locations offer a kids menu with smaller portions of popular items like tacos, quesadillas, and grilled chicken, usually priced $6 to $9. Kids meals typically come with a side and a drink. Ask your server for the kids menu when you arrive.

Can I order online or call ahead?

Many Diablo's locations accept phone orders for pickup, and some offer online ordering through their website or third-party apps. Call your nearest location to confirm they take orders ahead, or check their website for online ordering options.

Is there a happy hour or drink special?

Many locations run happy hour specials on margaritas and beer during afternoon hours, typically 3 p.m. to 6 p.m. on weekdays. Specials vary by location, so call ahead or check their social media pages for current deals.

What if I have a large group?

For groups larger than six, call ahead to let the restaurant know you're coming. While they don't take formal reservations, a heads-up helps them prepare seating and alert the kitchen. Large groups may experience longer wait times during peak hours.

Are there any signature dishes I shouldn't miss?

The carne asada is the standout—it's what the restaurant is known for, and it's worth ordering at least once. The pollo asado and any grilled fish special are also reliable choices. Ask your server what's fresh that day or what's popular with other customers.
