I'll kick this off with Alameda and East Oakland.
-Dynamite Cheesesteak, on Park St. in Alameda. Meh. Not bad, but not great either. All the usual stuff (bell peppers, mushrooms) costs extra, and it's kind of dry. Not enough fat in the meat, not enough cheese, too much bread. I've tried a couple times and it's just not doing it for me.
-El Senor Burrito, at High Street Gas and Food just off 880. I guess if you make tortas you've already got the ingredients, so why not? $5 gets you a cheesesteak **and** fries or rings, which has to be the deal of the month. The rings suck (they're the kind made of onion paste, not actual slices), but the fries are good, and so, surprisingly, is the cheesesteak. It's just a little bready, but everything is in there, prepared right, and tastes good. Plus it's right off 880 and the gas there is the cheapest in the area. Downside: no mushrooms.
-"Joe's Catering" lunch truck, on the old Alameda Navy base. This, chowhounds, is the winner. $5 gets you the biggest, sloppiest cheesesteak you've had in a while, jammed full of meat and onions and bell peppers and mushrooms and, I think, Swiss cheese. It's actually hard to finish unless you're hungry. The only downside I could find is that on a real cheesesteak, they slice the meat more thinly so it's easier to eat, and the peppers could have been cooked a touch softer. But it seems churlish to complain when you're getting about half a pound of steak for $5 and it lays the smack on everything else in the area.
This will be a tough one: they're in front of Creative Technology from 1 PM to 1:45 PM on weekdays. They're somewhere on the base for lunch and all afternoon, but I don't know the rest of their schedule. Maybe I'll find out next time.
They also have an Ortega Chicken sandwich that looks good, and the usual cold sandwiches and tacos. I'll report back with anything more.
The South Bay has Steve's...has anyone else found anything good up here?
