an obvious place i have to recommend is restaurant tori. i wasn't sure how to label it, though, since it is my fave for lunch, coffee, brunch, and breakfast. i don't visit every day, but several times a week -- enough to be such a household name that the staff are not always certain whether they already took my order or not.
tori is a great spot to meet friends for coffee or just linger by yourself in the corner reading a magazine. the clientele consists mainly of regulars and many of us seem to live in the neighborhood. there is something extremely comforting in seeing familiar faces on a regular basis even if i do not know them personally. somehow the place reminds me of my hangout in brooklyn, called atlas cafe, where the same crowd gathered daily over their laptops (me amongst them) and enjoyed the atmosphere sipping beautifully roasted coffee.
tori's big plus over atlas -- in addition to being located diagonally opposite my home instead of the other side of the atlantic ocean -- is great food. almost every sunday i stroll over with a group of friends for breakfast to enjoy a cheese and tomato toast, some scrambled eggs, and some loud chatter. their daily lunch menu usually has some good old home cooking and fresh fish and the serving size is generous. the famous meatballs are such a staple dish that when i was part of creating kortteliravintola kerttu in me olde hometowne of turku, we included a version of the dish on the menu, and it's been a huge success ever since.
strictly on a walk-in basis, they take no reservations, but sometimes are willing to extend their kitchen opening hours if you're running late with the munchies. they've improved their service speed significantly from a few years ago when it was excruciatingly slow, and now things usually go quite smoothly... unless the staff is relying on reino to help out, because then you just have to live with the warmest and sweetest waiter creating ultimate chaos.
