Sometimes you just want a nice beer in Vegas, and it turns out this place wedged between Aria and Crystals was a solid choice for some afternoon libations. We actually came here twice during our weekend trip, and it was a solid choice for both food and a wide beer selection (I think we even had champagne?). The style of the restaurant is fun -- it's got that modern pub look that's not trying too hard to look old, and there is a great little patio area for people watching. Although we did get some odd looks for sitting out there, but hey December in Vegas is basically summer to Seattleites like us!
One word of warning: if you're planning on using your Aria dining credit here you technically can't. I only found this out after checkout that the credit only applies to restaurants "in Aria." After about a half-second of stating my confusion to the customer service associate said not to worry about it and applied the credit anyway. So it worked out in the end, but c'mon, half of this bar is basically in the hotel and they are all under the MGM umbrella anyway.
