Been dining here for a year now. It's one of my daughter's and my favorite spots. The service is always quick and attentive and the food is very good. I usually get the Enchiladas Verde (Chicken Enchiladas with tomatillo sauce), it's my regular dish to order at most Mexican places. Hands down, La Unica's beats the competition- all white meat chicken, covered but not drowning in sauce. The salsas are great, especially if you like spicy, and this is the perfect place if you're in a rush- you can usually get out within 25-30 minutes. My only complaint is that parking can be a little cumbersome. Overall, it's the spot to go for Mexican in Harrisburg!
