Well, on the advice of others on chowhound, I tried the Burlington Fish House on Rt 3A in Burlington (in the same strip as Blockbuster Video. It was GREAT. Had fried whole-belly clams. The breading was perfect, the clams were sweet and tender and the portion was more than adequate. The onion rings were not overly breaded and had that sweet onion flavor. Wife had grilled shrimp which was nicely charred and had a great sauce basted on.
The dining room is pleasant with several HDTV's showing the Bruins game. They call your number and then you pick up your tray.
For both dinners, a bottle of water and a Sam Adams draught, it was about $32. Why drive to Ipswich?
