I paid a return visit to G&M last night, and it was even better than my initial visit. The new decor is not bad at all - it has much less of a 1950s feel, uses lots of wood, and the space is broken up into several dining room/areas. I sat upstairs over the bar, which was fine for a solo diner as I had a perfect view of one of the jumbo flat-panel televisions on the walls (I was able to watch the ESPN special about the USFL - the sound is of course kept off, but the captions are set 'on').
The crab cakes were excellent - the same size as before, minimal filler and broiled just perfectly. I found that avoiding a potato/starch side in favor of slaw and mixed veggies as my sides made the meal more enjoyable (and it allowed me to demolish the double-crabcake platter)
I had a nice chat with the shuttle driver on the way back to the hotel, and we talked about some of the other places near the airport (Timbuktu, Snyder's and a place I hadn't heard of, Mo's). He stated that he preferred more flavoring in his crabcakes, specifically from the inclusion of mustard and Old Bay seasoning. But, in hindsight, I think I prefer the unadulterated flavor of the crabmeat that shines through at G&M.
