he Beehive isn’t exactly unknown. Witness the lines to get in every night. The secret is when to arrive. Come by 8 p.m., just before the live music begins (there’s no cover) and you’re less likely to have to wait for a table. You can use the time to read the exhaustive list of champagnes and sparkling wines, the largest in New England, or order from the generous (and little-known) raw bar, with not only oysters and shrimp, but lobster and tartare. Then kick back and watch the rabble cool their heels behind the proverbial velvet rope. This is how the other half lives. Healy
