Stopped by Antonio's, the generally-okay-but-nothing-fantastic pizza joint on Flatbush last night, near the B/Q subway and that American Apparel monstrosity.
$1.25 doesn't get you much anymore, but they've got these gooey, cheesy, spinach-broccoli, stromboli-like pinwheel rollup things that really hit the spot.
Let them heat 'em up nice and hot, and they get good and crisp on the outside and have a nice mushiness on the inside. They serve a similar purpose to, say, a certain kind of knish, but even at Yonah Shimmel's, most of them are soggy and cruddy (if you've got a better knishery, please let me know). We're not exactly talking high cuisine here, and it's definitely not fresh spinach or broccoli, but at least they're still reasonably green and not overcooked. They can use a little perking up with salt and hot-pepper flakes, but for $1.25, they're a small snack triumph, and for $2.50 for two, you wouldn't need to buy (or, dare I say it, cook) dinner.
Up the street, Christy's has great patties that are also pretty darned cheap, but the veggie ones -- the only ones I eat -- went up from $1.50 to $2 when they moved. Still a bargain for what they are, but not the steal that they were before the move.
Not exactly nearby, and already much-commented-upon in these boards, my other favorite sub-$2 yumminess are the tamales on 4th Ave and 11th Street. Anyone who doesn't know about these should hustle over and grab a dozen. Extra bonus enjoyment points for bringing them to a bar that lets you bring food in, and snarfing them with good beer (my bars of choice aren't especially near the tamale place but are closer to me up on Flatbush, but I'm sure there are others).
Anyone have any other suggestions for ultra-cheap, slightly out-of-the-ordinary snacks (ie, not just pizza slices) in the Slope and adjacent nabes?
