I highly recommend the jumbo lobster roll at Robert's Maine Grill, across the street from Bob's, on the northbound side of Rt1 near the Banana Republic/Gap outlets. It was really good and worth the $$ to upgrade from the regular. I was so awestruck by its beauty, I took a quick picture with my cell phone and emailed the manager a day later with my high praise. The onion rings were also impressive.
Bob's Clam Hut has a decent lobster roll, actually, for a decent price. I know they've been slammed recently by many, myself included. But I was up there a few weeks ago and stopped in, and the food was better than I'd had the last time I was there. Fish-n-chips nice and fresh, crisp. Lobster roll good too. If you are willing to drive a bit farther north to Wells, Fisherman's Catch is outstanding.
