Whoa!! The 90s are making a comeback at Hyatt Regency in Cambridge during the month of July. As part of the hotel’s celebration of 40 years by the Charles, they’re offering decade-inspired specials at on-site restaurant Zephyr on the Charles. In honor of the pre-Y2K years the chefs have an entrée that’s all that and a bag of chips—the Asian shrimp salad is available for $19.76 and comes with Napa cabbage slaw, grilled pineapple, glazed shrimp, chili ponzu and cilantro. On the cocktail side, the bar team is stirring up a bomb diggity Long Island Iced Tea for $11 each. Relive the Clinton era sans the flannel, and call 617.441.6510 for reservations.
