A very cute bakery, Seara is run by some very nice Portuguese folks and make some very tasty treats. Bagels and loaves of bread are sold fresh and quite reasonably priced. They also have some very nice--in addition to mediocre--simple pastries.
The place is usually very busy, with a packed patio on warmer days.
Some of the staff speak only a little english but there's always someone else who can help out.
