I must have passed this place literally thousands of times, as it's just around the corner from my house (not sure why I keep missing all these great places only to find them years after they open, but I digress...). I guess I just didn't expect anything good among all those warehouses.
The place is small-ish, clean and the owners are super friendly. The menu is similar to that of California Sandwiches but the food is so much better! I'm in love with their veal sandwich (hot, with mushrooms and cheese, of course). The portions are large and very reasonably priced. On-A-Bun has definitely become one of my family's regular spots for a quick bite.
