Among the the controlled chaos that is East Ohio Street, right in the middle, near the Citizens Bank is the best little bakery I've been to for sweets of all kinds.
Amazing handmade, homemade donuts, seriously gluttonous gobs, cookies and really good looking cakes. A nice peaceful oasis to sit and watch the scenes of East Ohio St.
Don't get me wrong, I like East Ohio St. I lived and worked in Central Sq. Cambridge for years, and nothing that happens here will compare to the Central Sq regulars.
Great place to get a snack or something nice to bring to a gathering. Also a great place to get a cake for birthday, wedding, or any occasion. Polite, friendly staff, excellent baked goods.
