After fielding the question for the best lobster roll near Hynes, I decided to try out B&G Oysters in the South End.
Well, it was fantastic. First off, it's a really nice modern room - cool, but not cold. Nice bar area where I enjoyed my meal, and a pretty big patio/garden out back. (I was warm, and it was air-conditioned inside.) Sat at the bar so I could watch the shucking of the nearly dozen oysters they have available. (5 from PEI, a couple from Nova Scotia, and the remainder being West Coast, I believe.)
To start I had the New England clam chowder, which was brilliant. Creamy, but not too much, with huge strips (and one or two whole bellies) of well-cooked clam (toothsome, but not chewy), a sizable amount of lardons, and a few paprika-coated "croutons" (for a lack of a better word). A little dill tossed on top, too. Really, really good. Really.
As for the lobster roll, it was magnificent. A hefty amount of lobster, a little celery, and enough mayo to hold it together without being cloying. Some herbs tossed on top but they were more for color, I'd guess, as they didn't contribute much flavor (which is a good thing, in my opinion). The lobster was perfectly cooked and the bun was a proper one and grilled nicely. It came with some great homemade bread-and-butter pickles, a so-so cole slaw that had a slight Asian flair, and amazing fries tossed with herbs that included one with a licorice flavor. Trust me, it sounds gross, but it was actually fantastic. Gave them a slight sweetness, or, more appropriately, the perception of sweetness.
And so you know where I'm coming from, I'm a New Yorker who hasn't had too many lobster rolls, including 0 (well, now 1) in New England and my favorite here in NYC is Pearl Oyster Bar. Take that for what it's worth - I don't want to give the impression that I'm a lobster roll expert at all.
The total for the meal, including a very nice glass of gruner-veltliner, came to $42.75 including tax, but not tip. I'll definitely be recommending it to my Boston friends.
