This Starbucks location is located in the Bally's Grand Bazaar Shops. It's open 24/7 and it is huge. There is plenty of seating. Most of the seating is stadium type seating with benches. They also have an out door patio. The staff is very friendly and attentive to the guests. I do notice that they are under staffed sometimes when they are busy. They get your drinks out pretty fast though. Also, this location is not owned by the casino so they don't charge outrageous prices like the location on the Linq promenade does.
Definitely one of my favorite Starbucks stores. Stop by if your on the Strip.
