Anybody that knows me at all knows that I love Mexican cuisine so I was excited to learn about Casa Vieja Mexican Grill in downtown Nashua. Five of us came here for dinner recently and we enjoyed a fabulous flavor fiesta. The margaritas were most excellent too. Service was friendly and prompt, and the atmosphere was vibrant. The menu is loaded with amazing variety and culinary creativity. The Texas Fajita is a beautiful work of art, as is the Seafood Pina. I had the Carnitas with Green Sauce; the pork was cooked tender with a light crisp on the outside. We also had a variety of enchiladas, and Tortilla Soup as well. Highly recommended.

I’ve been here late night before but never for a meal. I just had my first meal here and I really enjoyed it. The drinks were amazing and food was delicious and decently priced. Will 100% come back

Great place for Mexican food. Hung out at the bar and received great service. The shrimp tacos were great, will definitely return when in New Hampshire.

Always a great experience! The margaritas are made fresh in house and never disappoint. The Molcajete is phenomenal and easily serves two. The camarones diablo is my favorite spicy dish and the heat doesn't take away from the rich flavor. Staff in the bar area is always prompt and friendly.

The place is beautiful inside, can sit many. Our waiter was attentive from the beginning to the end. The portions are big, I could not finish the chicken fajita, that meat tasted so good. Great price for a night out for two

Casa Vieja on 96 Main St in Nashua isn’t just a meal — it’s a party on a plate. The music’s bumping, the energy’s up, and the food? Next-level. Here’s the insider tip you have to try: Order the fajitas (any flavor — chicken, steak, shrimp, you name it) and pair them with the queso fundido. When that sizzling skillet hits the table, toss all the meat, peppers, and onions right into the molten, cheesy dip. Then pile it high onto a warm tortilla. Instant flavor bomb. The fajitas by themselves are — juicy, bold, and cooked to perfection. But when you blend them with that stretchy, bubbly queso? Game over. You just unlocked Tex-Mex greatness. Casa Vieja nails it — fun vibes, killer food, and a place where every visit feels like a celebration. Come hungry, leave happy (and maybe a little full of queso).
