Iridium's facade as seen in Friends
Iridium is a New York restaurant where Monica worked. She worked there during the first two seasons with Franny and met Paul the Wine Guy.
In The One With Five Steaks And An Eggplant Monica got promoted, but was immediately fired as she accepted a gift from the meat vendor, which is against the corporate policy.

It is also the restaurant where Joey and Phoebe go for dinner in The One With All The Cheesecakes.
The Iridium specials the day Joey and Phoebe go are prime rib, mahi-mahi and a very special lobster ravioli. Joey ordered the ravioli and Phoebe ran out of the restaurant to meet David for drinks.
