Hi Pete.
There really isn't anything cheap about Boston nor is there really any way to do Boston on the cheap. Seafood is extraordinarily expensive in and around Boston area. Even when you get out of Boston into places like Essex and Ipswich, seafood prices are still insanely high.
If you are looking for seafood anywhere within a couple hours driving distance of Boston, you can expect to pay anywhere from $13 to $25 per plate, per person just for the entree', depending on what you order and what's in season. Even the "seafood stands" are outlandishly expensive.
So, here is what I recommend. No BS.
Go find a hardware store and buy a couple of buckets, a hand rake, a hoe and a shovel. Find a beach, look for the eel grass at low tide and start digging. You will find more clams than you can eat.
At low tide, find a peer and chances are you will find mussels and oysters growing on the columns. For about $25, you can purchase a 12ft diameter casting net. Find a peer or a dock and cast the net. You will be surprised at what you will catch.
Or, for about the same money, you can buy a crab trap and bait it with a chicken neck to catch blue or rock crabs from a peer or a dock in between low and high tide. None of this requires a fishing license and I guarantee you and your daughter will have the time of your life.
If rolling up your sleeves and getting wet is not in the cards, go to any pier and find a local, small boat fisherman. The best time to find them is mid afternoon when they come back with their catches. In most cases you can buy directly from them in cash and save a ton of money. The only drawback is you are on your own to cook it, which can be easily fixed with one of those disposable grills and a few ingredients you can pick up at any stop-n-rob.
This is the real way to do seafood when you are in New England.
Good luck!
