Highly recommend this place for the entertainment value (didn't eat here) although the pours are top-notch.
My wife and received some recommendations to go here from our cocktail waitress at the Cosmopolitan so we wondered in through a non-descript entrance next to the Wicked Spoon buffet. RRL consists of 2 Rooms: the Main dining room with a bar & live entertainment, and a "Secret Room" which is reportedly very low key with custom cocktail creations. We were there for live music so we chose the dining room. It's open seating at the bar and around the bar, and you can order off their full menu anywhere in the main room. Otherwise, better make RSVPs for a table.
We grabbed the open corner bar chairs at the bar for literally the best seats in the house to catch the live entertainment (our bartender agreed). RRL's dining room is one big room, with either singers or dancers moving throughout the room while performing. Each area has an dlevated platform of sorts for the dancers. Views can sometimes be partially obscured.
Keno our bartender was superb and was kind enough to tell us what to expect crom the entertainment, and when. Most nights the entertainment consists of a 3 piece band: bass, drummmer, and pianist with 2 singers. Sets are usually for 15-20 mins every hour. We returned Friday night, and the slready good entertainment value skyrocketed to superb. Fri/Sat nights throw in another guitarist, another singer, and 3 awesome male dancers: a tap dancer, break dancer, and a way too-cool "Robot" dancer.
Libations are unsurprisingly pricey here, but well made. TIP: drink one of their 3 "Craft in the Bottle" drinks. They are each served in a unique take-home flask (makes for a great souveneir). We loved their "Old Dog New Trick" cocktail ($35). Their 3 flask-size drinks are actually a good value given it's 4 drinks + a flask ($9/drink).
The night zoomed by and was very memorable, especially the occasional "swooning" of one of the singers to my wife. Stop here for some relaxed fun and great entertainment. Ask for Keno if sitting at the bar, and tip him well.
