Clear Conscience Cafe (C3)

Occupying the front portion of Harvest Coop (where health-conscious locals load up on organic tomatoes and cereal), C3 serves soups , paninis (try the Peanut Butter and honey ), and organic baked goods . Read more

The name is so crazy pretentious I nearly gagged checking in here, but the food is good - albeit overpriced. The turkey/apple/Brie sandwich is worth it though. Everything here tastes from-the-earthy.

Get the Breakfast Egg . Best bagel sandwich in Cambridge. The ham on it is amazing.

C3 can call itself C4 (the fourth one standing for Closed) until it reopens across the street @ 580 Mass. Ave.

The C3 grilled cheese sandwich is really good. You had better get one. Or else...

Stick to coffee , which is great. The espresso drinks are a bit weak and not always well crafted. Yummy soups !

Baked goods are delicious and so are the sandwiches . Enjoy!

The Purple Berry tea is amazing and piping hot!

Their Arnold Palmers are the real deal.

have the roast beef sandwich 'for here' - you get a fantastic bean salad with it. I don't know which is better...

Love the chicken panini but the price is highway robbery like most sandwich shops in central.

Sweet po-tay-tow sandwich is bomb. Enjoy!

Rice milk AND Stevia?! A healthy gal's dream cafe ! PS staff is sweeter than cupcakes .

Their wifi only lasts an hr here so if u actually have work 2 do go 2 starbucks

Shop local. Tip well . Pay cash.

Great bagels and organic egg sandwiches .

Add a shot of espresso to your chai latte here. You can taste the organic !

Amazing vegan chocolate chip cookies . NOM!!!

Don't forget to check out the Harvest market in the back!

Lovely piano jazz on the radio .

They have free wifi for 1 hour.

On the MBTA outbound side of Mass Ave.

the veggie sandwich is amazing. eat it on the comfy couch !

try the grilled cheese sandwich - seriously the best thing ever.

Make sure to bring a friend. Everybody's judging.

I'm digging the snacks !

They aren't used to being busy. If you come in around lunch , be ready to wait 20 minutes for a sandwich .

Good food, coffee and seating, but way overpriced. Read more

Free wi-fi but only for an hour.

Great organic coffee ...

Sadly, now closed. :(

Good food but very expensive for just a sandwich .
