I went here last month with my girlfriend on our anniversary trip. It was a murder mystery themed menu, with drinks built around different suspects of the murder. The fun part is that as you order certain drinks, you will get clues to slowly figure out more and more of the murder mystery story.
Usually, I've had bad experiences with these "gimmicks", where fancy presentation and backstories didn't add much, and were there to justify a charging through the roof.
However, not only was 4e Mur competitively priced with nearby bars, they deliver so much more. The drinks were well thought out balances between the sweeteners and be base liquors. The presentation of the drinks that included the clues were fitting, and not distracting from the solid drink liquid.
On top of all that, the wait staff was extremely interactive throughout, making solving the mystery even more fun. They really gave me the feeling that they were all a part of making this fun experience, and were all really proud of their work.
All in all, 4-5 hours later, having solved the mystery, and extremely happy. The bill wasn't anywhere near as bad as I anticipated it to be. While I wouldn't call their drinks cheap, they most certainly were very fair in terms of pricing the drinks they delivered.
