When I arrived at 1900, the lounge was full and on a wait list. I had been up since 3 am and had an overstimulated newborn so I asked to upgrade to the first lounge for $45.
The lounge was completely empty and staff were so kind and attentive. I ordered the Brussels and steak tips and while I wouldn’t compare it to the quality of the Delta One lounge, it was definitely a step above a standard lounge.
For my situation, it was well worth the upgrade for a nice quiet space with good food and drinks.
Here is a full picture of the menu for anyone interested!
