First time I went: Meh. Not great, not bad. Just okay.
Second time I went: Really? We were standing there waiting and you didn't tell us our drinks were ready. Bad customer service mojo.
Third time I went: Meh again. At least this time I was told when my drink was ready and the cashier was nice enough.
There's a better one up the street on Ft. Apache & Tropicana. Just a few blocks away. Go there instead.
