At the time of this post, Mimosa has 62 one-star reviews, which far outweigh any other rating - the numbers speak for themselves, folks. Please, I implore you, do yourself a favor and avoid this sorry excuse for a restaurant.
As others have already written, you're forced to scan a QR code on the table, which pulls up a digital menu where you must place an order. My wife and I had a short layover in Minneapolis, placed an order for two meals and two beverages. Shortly after placing the order, a waitress came out with the beverages and stated the kitchen was closed. I asked why we were able to place an order, to which she could not provide any logical explanation. I stated if the food order is not being fulfilled, we also do not want the beverages and inquired how to get a refund.
She insisted there was nothing she could do and that I needed to request a refund via the digital receipt I'd received on my phone, to which I did. A short time later, I received an email response from Mimosa / OTG stating the kitchen is open for another 30 minutes. Completely ridiculous given the staff at the restaurant insist the kitchen is closed and that I need to request a refund, for which apparently, they're helpless to offer any resolution. The gentleman behind the bar then proceeded to patronize me by smiling and acting with a completely over-the-top and clearly fake politeness and telling me to have a nice day. I truly empathize with travelers who have to put up with and deal with such unscrupulous and dishonest business practices, coupled with such nasty people as this young man.
I then responded to Mimosa's email stating the kitchen is closed and the restaurant won't fulfill the order. The "manager" then wrote back stating he would issue a refund that would be processed in 5-7 days. Truly an inconvenience and annoyance, but had it been resolved there, I wouldn't be taking the time to write this post.
But it wasn't resolved. It's been 11 days and the charge is still on my account and has posted. Mimosa / OTG and the "manager" who replied via email have done nothing to resolve this. I also added the hello@otgexp.com email as the Business Owner has suggested in other negative Yelp reviews, and that too so far, has done nothing to resolve this situation.
In reading other reviews, I'm not the only person who's been charged for orders which were not fulfilled, and also did not receive a refund.
To break it down -- customers are forced to place an order via a website by scanning a QR code, meanwhile the staff at the physical restaurant location insist the kitchen is closed, while the digital store / website indicates it's open, thereby placing customers in the middle of a (likely intentional) "miscommunication" between the digital store and the physical restaurant.
These type of unscrupulous business practices and fraudulent charges are completely unacceptable. In taking a quick look at Yelp and Google, it's quite clear this is not an isolated incident. Despite having it in writing that they would issue a refund, Mimosa / OTG did nothing of the sort and have not responded to further inquires.
Since then I filed a claim with my bank disputing this transaction since the order was not fulfilled and the company has done nothing to resolve it, and it's now well beyond their stated timeframe of 5-7 days. Do yourself a favor, go anywhere else in the airport. You will be saving yourself time, money, a headache, and you might actually get something to eat.
