Love the concept of Hostile Grape! It's a fantastic wine tasting bar. I've only been here a few times and they've all been quite enjoyable experiences.
It's hidden in the basement of M Resort in a dimly lit room. There's literally an endless number of wine bottles (of every kind imaginable) in every direction you look... My kind of bar! There's wine stations where you're able to help yourself to an automatic 1 oz, 3 oz, or 5 oz pour. The prices greatly vary and can get expensive for a small tasting.
In order to even sample the wine, you need to purchase and load up a card from the bar. There is a $5 activation fee (which I think is unnecessary) and a requirement of placing a minimum of $25 on the card.
They also have live music on the weekends to top off the intimate wine tasting experience. A guitarist/vocalist to set the mood.
As Hostile Grape is ultimately a wine tasting bar, I wouldn't recommend this place for a wild night out. The pours add up quickly and you may find yourself loading another $25 onto your card. My coworker hosted her birthday party here once and I've also gone with a group a girlfriends. It wouldn't be a bad place to go on a date either...
Overall, as mentioned earlier, it's definitely an enjoyable wine tasting experience! For wine lovers wanting to indulge and have a classy wine night, Hostile Grape is a phenomenal choice.
