The first day of each month is always a theme day for members of City Daily Photo, and for May, that theme is Let's Eat. You can see how others are interpreting this theme here.
Di Rienzio's is a small grocery in Little Italy, running the store out of half of the ground floor of this quiet house. It's a busy place, though, one that sees a lot of foot traffic each day. It's been in business for over forty years, run now by two brothers, and a lot of their daily business comes from sandwiches, ready-made (I recommend the steak or chicken parmigiana) or done at the deli counter, and pasta to go. The store is an Ottawa institution that's been profiled in national newspapers.
3 Tarts is a bakery based out of the downtown core, and I can tell you their fare is very tasty.
This permanent location for Beavertails is down in the Byward Market. It was just about to open when I was down there a few days back. A Beavertail is a local tradition- a flat fried pastry, topped in various ways.
Stella Luna is in Old Ottawa South, specializing in gelato.
And just down the street is Life Of Pie, which moved over here from up the street last year into a space that allowed them to put tables in for dining. The shop specializes in dessert and dinner pies, as well as baked goods, and offers daily specials.
