Definitely go there!
Ok - where was I - I guess the best way to do this is to list the restaurants and our opinion of them. I can't remember when we did what, so here goes:
Original Seafood - I believe in Dennisport - I can't believe no one has reviewed this place. It's been around since the 50's and the fried food was wonderful - pillowy soft fried scallops with a light crunchy coating. Excellent fried clams, fried haddock sandwich. They are right down the road from Kreme n' Kone (sp?) . We wanted to try there too, but went back the 2nd time to The Original Seafood Co. because we couldn't imagine the K & K being any better. Next time we go we'll compare, but really - I think it would be dang near impossible to get better. Absolutely recommended.
The Cape Cod Claddagh Inn - We wanted steak, it was close by. They didn't have steak that night, so we had burgers. It was ok. This is definitely a "local" bar - service wasn't that great. I think it'd be a much better place to drink and party (they had Karoke).
Ardeo's :
http://ardeocapecod.com/menu.html We had a gift certificate for here. It was good - Bob loved his lamb and chicken kebobs, and I had something totally not like I would normally get: pork medalions with apples in a amaretto sauce - it was very different, and very good. The sampler appetizer is way too much for two people. At first I thought this was a chain - it has that look and feel about it- but it appears that it isn't. I can see that happening in the future though.
Salty's :
http://www.saltys-capecod.com/index.htm Twin Lobster Special for $19.99 could not be beat, decent fried scallops as well.
Marconi's BBQ - we couldn't resist stopping in for a pulled pork sandwich after seeing the stacks of wood and smokers outside. It was very good, but not my husband's

I am completely biased on this matter!
Young's Lobster -Rock Harbor - it was recommended to us to go to Captain Cass's in Rock Harbor-both by Bob's parents and a great local guy named Ted, which we had the pleasure of having drinks with - only to find them closed. However right next door is another small shanty called Young's. Positively delicious lobster roll. Big white chunks bound with very little mayo on a Bun. Fresh as can be. A bargain too at $8.95 each. Not sure if that price will go up as it gets to be "in season" on the Cape. We went the week before everyone usually arrives. Cap'n Kass (not sure of the spelling) will have to wait another year. They are only open on weekends before the summer starts.
The Wooden Shoe - a bar in Dennis - off the beaten path - we didn't eat there, but it is a great little place- reasonable, nice people- they don't price gouge you for drinks - just a great time. The owners are really great. The first time we went to the Cape they had just opened and we joked about the tee shirts they came out with: it has a big picture of a cartoon-y lobster with EAT ME at the Wooden Shoe on the front. 5 years later, the tees are alot more subdued, but we all had a good laugh when we said we still had the original shirt! A great place to hang out-reasonable and fun company.
Ok - time to go home - more again later - I still have to tell you about our ride home!!!! 3 roadfood stops in one day!! Have a good night...Sue
