My family and I will be flying out of SFO on a late Sunday afternoon. I thought we could pack some sandwiches to eat on our flight. We'll be staying in the Union Square area, but can walk as far as North Beach, the Ferry Building or SOMA if necessary.
I'm hoping to find good hero/hoagie sandwiches, something that will hold for 4 or more hours, with great cold cuts, cheese, veggies on crusty bread. A Yelp search turned up Sammy's Smoke and Snacks, Giordano Brothers and Mario's Bohemian Cafe, but I was wondering about any other recommendations Chowhounders may have. Thanks in advance for your help.
