Nearly a year into its run, “Hello, Dolly!” is buoyantly better, brighter, and tighter than on opening night.  Bernadette Peters gives a stellar, steadier, and more grounded performance as Dolly Levi, alongside replacements Victor Garber, Charlie Stemp, and Molly Griggs—and Gavin Creel and Kate Baldwin, and the ensemble, are better than ever. This is the best musical comedy on Broadway.  If you haven't seen it, get tickets now; if you have seen it, it's worth checking back in.
