Good takeout is a challenge. The Dolphin does a pretty good job. Nothing is extraordinary but nothing is bad either. Think fresh fish dishes, some beef as well. A bit pricey for the quality. Cooke's in Hyannis is good fried fare. Their broiled dishes aren't great although the swordfish is pretty good. Problem is fried seafood doesn't travel all that well. Avoid the clam plates. Crazy at $19 and they buy the cheapest clams possible with very tiny bellies. You could always go to any fish market and have them steam a couple of lobsters for you. Pick up some coleslaw and you have a decent meal. On Main Street in Hyannis there are 3 very good Italian/American choices. Alberto's, Fazio's and Colombo's. Alberto's is the most expensive but the best of the three in my opinion.
Can't leave the pup in the car for an hour or so? Shame.
Momo in E. Sandwich has good options for take out but pricey. I heard good things about the "
new" Amari but cannot comment. Thai on Independence in Hyannis, close to B'Stable? Not sure Fromage a Trois is open on the weekend..near the train stop on 149 in B' Stable they did have nice pastas and Burrata but it looks closed up as I mentioned.
