Here is a short summary of Opera Bar:
Ok... I like Opera Bar, it's really pretty and the drinks are good and the food is nice and blah blah blah but seriously, it is so ridiculously pretentious, the staff are mostly lovely but GOD they are so disorganised and lazy. I swear every time I go something i've ordered is late to the table. I get it, you're busy, but how are you charging like... $25 for a simple cocktail and not have enough staff? sort it out.
Drinks are over priced, which attracts a crowd that believes money=class, the service is sub-par and the food is only just above average. Views good but the bar didn't do that, Australia did. Music is never great it's like... top 40's hits mixed in a wok by a kids party DJ.
The two stars are for positive reinforcement. Use it to motivate yourself to be good.
