Exxon, a well-known business, has garnered positive reviews from its customers. The store is described as a 24/7 taco shop, offering a variety of delicious street tacos that have been voted the second-best in Dallas. Customers praise the store's cleanliness, lighting, and fast service. The owners, who speak both Spanish and English, are known to be friendly and welcoming. While the gasoline prices are considered favorable, the app may not offer significant savings unless a large volume of fuel is purchased. Overall, the consensus is that the tacos are exceptional, with great salsas and a no-nonsense approach to providing quality food at reasonable prices.
