Reservoir Lounge is one of the nicest jazz bars in the city. The live music being played is always great and provide a truly unique ambiance. The crowd that comes out are here to party and are not shy to dance the night away or show their significant other how much they love each other (PDA). If you have issues with PDA then stay clear because people here are not shy. If you don't then jump on in as the drinks are good, service is fast, food tasty, and music is cool.
It's hard to describe what the decor looked like as it was very dark inside but from what I recall it is very nice. Lots of candles, dim lighting, abundant amounts of dark wood, small tables with white table cloths, small stage, exposed brick and a 360degree bar. It was nice and cozy inside as there isn't much room and there are a lot of people. If you want to snag a table here I recommend coming very early or booking a reservation. On live music nights there is a $10 cover charge.
Overall, Reservoir Lounge is a very cozy cool jazz bar in the city. Drinks are a little pricey and the cover charge doesn't help much but it is a lot of fun if you enjoy jazz and an outgoing crowd. Don't be surprised if many people approach you looking to talk, seems to be the thing to do here since it's so cozy. Bring some cash you're going to need it and come early so you won't be disappointed.
