Why not just go outside the hotel and walk one block South to Duke's? You can get the best $2.00 breakfast you ever had! Clean, safe and much like a Panera Bread.
Likewise, one the same block at the Marriott, on the South side, walk West for a great dinner or lunch at Barrymore's! Last time we had lunch there they were giving out free Matinee tickets for plays! We went! Great food and not expensive!
Like the Hilton on Ave of the Americas and the Sheraton on 7th Avenue, the Marriott Marquis is a convention hotel. All three are extremely popular venues for trade conventions, association meetings and company promotional events. Quite honestly the Concierge Lounge in these hotels are not a place of quiet refuge, by their very location. Add food and alcohol, they will be places to gather and be very animated.
Try the St. Regis the next time or one of the college clubs that hosts your alums. My personal favorites include the Princeton Columbia Club, the Harvard Club and the University Club. All three are hidden gems that offer a nice balance of animation privacy and quiet refuge - where you can just read the paper or a book as cell phones are prohibited.
Concierge food offerings is another matter. As one Insider observes, "chicken strips two nights in a row." What I'm gathering is that brand standard for top-of-the-line Category 8 guests is disappointing. That's ~not~ a very good sign, folks.
Famous and popular as it is as the feature revolving restaurant in New York, even The View Restaurant is not the place to enjoy culinary delights or great service. We go there once in awhile to celebrate a birthday or a special occasion like Mother's Day or Father's Day when you can park FREE on the street on Sundays. It's a place to bring out-of-towners for the view and a cocktail.
In addition to the college clubs, Limoncello at 777 Seventh Avenue in the Michelangelo Hotel near the Equitable Building is a wonderful upscale place for a memorable breakfast. The venue is classical and sophisticated but not stuffy and the food and service is impeccable.

I'm glad you enjoyed NY city of my birth! Anyway, when you have a chance, do consider sending Customer.Care@marriott.com a note about your experience - positive and not-so-positive. It's really the only way they are set up to track how a property is doing by directly linking a guest confirmation #.
