What an absolute delight! This charming little restaurant completely exceeded my expectations. From the moment I walked in, I was greeted with warm smiles and the kind of cozy, welcoming atmosphere that makes you feel right at home. The food? Fresh, flavorful, and clearly made with love—but the real star of the show? The ice cream. Homemade, creamy, and bursting with flavor, it’s easily some of the best I’ve ever had. I tried the vanilla and chocolate both were smooth, rich, and perfectly balanced. You can tell they don’t cut corners here; every bite felt like a treat crafted with care. Whether you're coming for a full meal or just stopping in for dessert, this place is a true hidden gem. If I could give more than five stars, I would. Already planning my next visit! One of the things that truly sets this place apart is the staff. From the moment you walk in, you can feel the pride they take in both their work and the space itself. Everyone is incredibly friendly, welcoming, and genuinely seems to enjoy being there—which makes all the difference in the experience. The service is always attentive but never pushy. They’re quick to offer suggestions, answer questions, and check in without hovering. You can tell they actually care about their customers and want you to have a great time. On top of that, the restaurant is immaculate. Clean tables, spotless floors, and even the bathroom was tidy and well-stocked. Little details like that really show the effort they put into maintaining a high standard. It feels like they treat the place with the same care they’d treat their own home. You can tell there’s a real sense of pride behind the scenes, and that’s rare to find. Big shoutout to the team—they’re the heart of what makes this place so special.

This place is awesome. If you want to feel like you are on vacation, get some seafood, ice cream, sit on benches, but not actually travel anywhere, go to Groton and eat at Johnson’s. The food is great! And the restaurant is fun.

We are from Cape Cod, and stumbled across this gem today. The food was excellent as well as the fabulous homemade ice-cream. My wife loved the fish & chips plus the portion was huge! My turkey club sandwich was excellent! A great place and inexpensive. Old school family place.

The food was excellent. For a party of 7, between the fried haddock, steak bombs, greek salad with chicken, fried clams, and fish sandwich, everything was delicious. The restaurant is rustic, which makes it famous in its own right. The majority at my table were well over 70 and decided that Johnson's is now the place to go. The ice cream is amazing and there are endless flavors. The atmosphere is relaxed and many families dine here. Not as a complaint, but as a note of commendation: There were a few mixups in the order, perhaps due to youth, but it seems that the mature management cleared it up fast. Thanks for a nice meal!

Great Memorial Day lunch. Yummy burgers, seafood & ice cream. Quick and friendly service even though they were packed.

I haven't been here since I was a kid, and coming back was a treat. This is classic New England comfort food, fried seafood, burgers, chicken fingers, fries, dinners, ice cream, all the basics! And the best onion rings I've had in a long LONG time. Kind of limited parking and only a handful of family-style picnic tables though... Plenty of open seats when we were there, I'm not sure how it is all the time. But it's worth the trip... If you love that kind of food and atmosphere as I do, having grown up with it, then definitely stop in.

Great food and ice cream! Order up front and Seat yourself. Can get busy since all of Groton loves this place haha

As a child, my family used to drive by Johnson's Restaurant & Dairy Bar in Groton, as we drove to & from our beloved 4-H Camp Middlesex in Ashby, MA. A special treat every summer was stopping for an ice cream on our way home. Fast forward MANY years & I still love going there for an ice cream. I've never actually had any food here , but I know that their ice cream is always delicious! I especially love their peppermint stick!
