The Restaurant at Ambassador Chicago, JDV by Hyatt

"The location is as stellar as always, and the legendary Pump Room restaurant is still there, though the design is all new"

"The Pump Room, a dark and clubby celebrity haunt since the 1930s, is now an open and airy Jean-Georges Vongerichten restaurant, with a galaxy of gently glowing orbs suspended like planets throughout"

"After hours, the restaurant becomes a bar with a DJ, tapas-style dishes and a resident mixologist"

"The one concession to the swish life is Jean Georges' revamp of the legendary Pump Room restaurant"

"This “stunning” Ian Schrager boutique “tucked away” on the Gold Coast is an “elegant redesign” of the old Ambassador East, with a "friendly" staff that offers “prompt” service and “stylish” rooms outfitted with Frette linens and flat-screen TVs; adding to the appeal are free WiFi, iMacs and outlets in the lobby, free loaner bikesand the “beautiful” Pump Room (a former “stomping ground of Frank Sinatra”), which flips from daytime restaurant to nighttime “hot spot” where you can “grab a drink and people-watch"

"Located in the Gold Coast, surrounded by million-dollar mansions, the property has managed to woo its neighbors, with whom you’ll rub elbows at the popular Pump Room restaurant"

"Or make like Frank Sinatra and Mick Jagger by hitting the glamorous Pump Room bar-restaurant"

"Its Pump Room restaurant was the city's first posh, post-Prohibition, celebrity hangout (everyone from Fred Astaire to John Belushi has come)"

"Highlights include a restaurant by a well-known chef and a European coffee bar, though breakfast isn't included in standard rates and its pricey as an addition"

"The Pump Room restaurant is still operating in this hotel, though it has seen some changes"
