Best little sandwich shop in Mississauga hands down. Let me preface this with the fact that if you work in Mississauga, your food options for lunch are pretty limited - so I'm not telling you King Street yuppies to make the trek here for some paninis, but if you're around the area, then this would make for a pretty darn good lunch.
Porta is so much better than Panera in terms of the quality of food you're getting for around the same price. Sandwiches and salads are assembled in front of you. If it's your first time here, salads are ordered on your left near where the drinks are displayed, and sandwiches are assembled on the far right side. The cash register is in the middle of these two.
It's pretty crowded during lunch hours but they work quick so there's never a long wait for food. There's not much seating inside so grab & head back to the office to eat. They have extra outdoor seating though when it's warm out! This place is located within a lot of small businesses that strangely looked like retirement homes to me.
I've been here countless times for lunch and so have the bulk of my co-workers. I usually get a different sandwich each time and it's always amazing, and I always pair it with their vegan tomato soup. Try out anything on the menu, it'll be the best lunch bite you've had in Sauga!
