I posted about Cafe da Fazenda in Everett ages ago when it opened. I have been back a few times, but not in a while and somethings have changed. Its a small corner cafe/restaurant on Main Street near Belmont St. Since they opened, they are doing a steam-table lunch. $6 for a normal size lunch box, $8 for a large (good for 2 people), and if you eat there they have a $6 all you can eat. Note that at all Brazilian places fixed price lunch boxes ('Marmitex') require that the staff there make the box for you, otherwise its $4.99/lb (an option if you only want to get a bit of meat or something). The food was pretty homey and today's offerings might not be that exciting for most hounds (meatballs, brazilian style stroganoff, frango empanado (fried breast of chicken), and something else). But its a good example of the style, everything was home-made and fresh, plus this is the way Brazilian eat.
They still have a bunch of salgadinhos and will fry pastels (4 or 5 flavors) to order, I didn't try them, but they were pretty good in the past. A friend insists they bake the bread there (and got it hot), but I think they get a delivery from the Brazilian bakery in Framingham (it was in a basket, but I saw a plastic bag lining it and all their other baked products are from there). They do a lot of catering for parties such as suckling pigs, offer a boned stuffed chicken (unusual here and even offer this for turkey too). Haven't tried their pizzas and I recall they used to have a bunch of caldos (soups) which they could heat up and serve, but didn't see this today.
Another restaurant of this style is Broadway Cafe on Broadway, near City Hall and Dunkin Donuts. They have a slightly larger bakery offering, as well as salgadinhos, and if you look at the back page (I think) of their menu they have a couple of variations of made-to-order plates: a fried steak, chicken breast, shrimp and peppers, maybe liver... all for $8-10ish (shrimp might be a bit more) and can do two people (no steam table, the plates are made to order). Like Cafe da Fazenda really simple Brazilian beans, but I found them perfectly seasoned the last time I was there. That last page menu wasn't translated last I saw, but if you point and ask questions communication should be that hard.
Also in Everett JC Market on Chelsea St does the steam table thing, as well as having a butcher and pretty complete Brazilian market. The food was pretty good (and simple), but not quite as good as other. There also is a cake baker a few doors down from Cafe da Fazenda (Cake and Cia) which looks to have some other offerings, a Brazilian butcher on Main around there which had some prepared food (didn't look too exciting), and one new place further down closer to the rotary which I think is along similar lines.
