There are two Burger King's that I generally visit when I'm at the Airport in Vegas.....one in the C Gates area and the other is in the A/B Gate area. This review is for both of them......
They're always busy, so it's not always guaranteed that you can "grab n go" with the food. The seating area in the C Gate area can also get very busy.....the seating at the other location is usually open because the customers at the A/B Gate location usually get their food and go to their gate since it's at a fork between the 2 gate areas and there's still a 2-3 minute walk to the actual gate. Keep that in mind if you're planning to grab a bite before your flight.
The food is.....well, it's fast food and doesn't taste any different than the locations outside of the airport, just realize the cost is 50% higher. The service level is decent, not great.
Overall, it's a solid place to grab a quick bite and deserves the 3 Star rating in my book.
