Seven Subs
Absolutely fantastic sandwiches and great portions. The larges are probably enough for two meals (unless you are unusually hungry), and the prices are very reasonable for the quality. As a bonus, they also deliver.
Santoro's Of Malden
This is a hidden treasure, definitely. It's not much to look at, but if you want a seriously good sandwich (amazing Italian meats!), then stop by Santoro's
Prana Power Yoga
I really love Prana, and the Cambridge studio is the largest of the three locations. I've always gotten a spot in the classes, even during the busy 31 in 31 months (31 classes of yoga in 31 days for $131). The instructors are knowledgeable and friendly, and the atmosphere is truly relaxed. This is a great yoga studio.
The Sevens Ale House
This place is what they are describing in the Cheers theme song. It's friendly and low-keyed; the food is good, and the atmosphere is comfortable. A great little sports bar.
Blue Shirt Cafe Inc
I went here for the first time the other day and it was great. The selection is incredible and the prices are reasonable. Try the vegetable curry wrap - delicious!
Boston Burger Company
The burgers here are insane. I had to eat mine with a knife and fork because it was absolutely huge. I also recommend getting the sweet potato fries. You'll probably have to bring some home, but that's never a bad thing.
Buddy's Diner
Buddy's is just an incredible place to go for a no-frills, old school breakfast. It used to be billed as a truck stop diner, but it has been repainted and renamed, without losing that same feel. The place is tiny, but the plates of food are huge, delicious, and inexpensive. The coffee is simple and strong, and the service is friendly and efficient. I love this place.
Corporate Cafe
Corporate Cafe is surprisingly good, considering it doesn't look like much. The food is prepared well and the prices are reasonable. It's a great find for quick lunch in Charlestown
Esperia Grill
This place is fantastic! It has a great selection of really hearty and delicious wraps and sandwiches, plus the meat is cooked to perfection.
Cafe Rustica
I really love this place both for the quality coffee and for the convenient hours. While most places close early, you can always get something here!
