Tacos El Rey has great Mexican food and great prices. They do the majority of their business through the take-out window, which usually takes about 15 minutes per order. You can also dine-in. The dining area is comfortable and large enough to accommodate a group without causing other customers to leave.
The Enchiladas, Sirloin Burrito, and Nachos El Rey are my personal favorites. The hot salsa / sauce really is hot, so if you like a little spice in your food, go for it. If you are wimpy about spicy food, you will definitely want to steer clear.
