Last day of March, bundled up in a big winter coat walking through the South End, I thought if it weren't for the weather, I could live in Boston again. Boston's getting better and better. We'd seen Doe, my book agent, Saturday night for a little "tequila research" and she asked if I was a Barbara Lynch fan? I wasn't sure how to answer! She said I had to eat at B & G Oyster Bar on my way out of town Monday. Yes, open for lunch. No reservations! All set! I loved B & G the moment I walked through the door. Basically a long grey marble bar lined with crisp white napkins and wine glasses. Immediately I thought "This is the kind of restaurant I wanna have." Sixteen different varieties of impeccably fresh oysters, lots of them from the icy cold local waters. I settled on a cool dozen, -- four Island Creek from Duxbury, very plump and briny with a sweet buttery flavor, known as the oyster that never spawns and my personal favorite! Four large, exceedingly salty Pemaquid from Maine and 4 Ninigrets from the Salt Ponds of Rhode Island. Smooth with an underlying sweetness and a pleasantly mild salinity that defies their Salt Pond upbringing. A glass of crisp Petit Chablis. Call it heaven! Oyster heaven!
