The old GF lounge is a temporary "Polaris" lounge. I use the quotes because it is actually inferior to a normal lounge, let alone a First or Business lounge. But if you enjoy sharing that relatively small space with ~100 United J passengers along with 50 or so Lufthansa passengers, and fighting over a few scraps of food, go for it. Of course, they might not let you in, since they fill up before the major flight banks.

Aren't you glad you chose United?
