Yes, their drinks are crazy overpriced. Yes, the service is average.
However, the view is unbeatable, the patio has a nice vibe (especially on a Monday night when it's not as busy and there's free cover) and their margaritas that come in the perfectly instagrammable sand buckets are delicious.
So while it's not a cheap place for drinks, you're paying for a premium view on a chill patio and I think it's worth it every so often.
